There were certainly logs. But perhaps you meant log entries specifically related to what you are looking for.
I seriously doubt that the computer wouldn't log a login event for a remote user.

hi, i developed an application in .net 2008 3 years back and hosted in iis 6. its running smooth. but far past 10 days particular user facing problem. he getting dead slow with application. whenever he try's with different machine, for his login alone, its very very slow and sometimes timeout happening. its form authentication.what will b the problem? plz help

Is this user on your Domain or an external user? I'd assume that you're using Windows Authentication, so it should be easy to trace back through debug logging.
Were there any changes performed prior to this slow period? There are a large number of variables that could lead to authentication errors, but haveyou reviewed Event viewer on the box hosting iis 6 or one of the DCs?

I originally posted this in the "Web Programming" forum and in discussions over there it seems that the issue I may be having is related specifically to the Exchange server I'm trying to use. I'm going to re-post my messages over here in the hopes that someone will be able to tell me why I can't do what I'm trying and why there seems to be inconsistencies in the data that I've been finding. Sorry for the long post, but I'm just trying to post everything I already asked in the other forum and the only thing anyone was able to suggest what that it was some sort of network security issue and that I needed to ask someone who knows Exchange very well. Thanks in advanced for any help/suggestions/solutions that you can provide. This is something very important to an application I'm developing and without it I lose a major function.
Below is a combination of post I had written over a 2 day period based on additional information users were asking for. I cut it back some, but I just want to make sure I provide everything I can:
I'm a VB.NET developer and I like to expand by knowledge by trying to program things from scratch that are already implemented in the the.NET framework. My current project is programming a SMTP server using just sockets. I've already read the RFC on SMTP and my company has an Exchange Server (2007) that I was going to use for testing.
The web address of the server is exchange.mycompany.com and I used reverse DNS to get the IP adress. The domain name does have a MX record a well. From the command prompt on my computer (which is running Win7 Professional) I tried using telnet to connect on port 25. I tried using the domain name as well as the IP address, but both times it said it couldn't connect to the server on port 25.
I checked the settings in Outlook and the port is correct. I then tried connecting on port 110, and some other ones that are sometimes used, and it gave the same error message.
Next I connected to the Exchange server through VPN and tried telnet again on port 25 and this time it worked. However in the SMTP banner it said remote.mycompany.com instead of exchange.mycompany.com. So I disconnected from the VPN and tried the telnet again on all the ports I initially tried but used remote.mycompany.com but again got the same error message. I did an IP address lookup and remote.mycompany.com and exchange.mycompany.com point to the same IP address.
I then used mxtools.com and dnsstuff.com (I think that was the adress) and used their SMTP tools to see of they could connect. I entered mycompany.com as the domain name and they looked up the MX record, which returns exchange.mycompany.com as the SMTP server, and both tools were able to connect with no issues identified.
So my questions: 1) If the MX record list exchange.mycompany.com as the SMTP sever, why does the banner return remote.mycompany.com? 2) Why can't I connect the SMTP server through telnet unless I'm connected through VPN, but the two websites I used to test it the connection worked?
Obviously the server works because because the two websites can connect to it, I can when I'm in VPN, and other servers can because I receive email on my corporate account. What could prevent my computer from connecting to the SMTP server through telnet when I'm not on VPN. I should also mention that I even tried turning off all my anti-virus software to make sure that it wasn't blocking it.
I was thinking maybe because I don't have a domain name so if the Exchange server tries to lookup the IP address of my computer there is no MX or PTR record. Is this something SMTP servers look for?
Just today I also found something that I don't know how to explain or how it may affect this. The MX record for the server list exchange.mycompany.com. However, even when I'm on VPN, I can't connect to the SMTP server using that address in telnet or the IP address it points to. I have to use remote.mycompany.com, which is shown in the SMTP banner and points to the SAME IP ADDRESS. Is there a setting in Exchange that makes it script only request coming from this address? If so, how do the online SMTP tools discover this subdomain when I only gave the tools the domain name (mycompany.com) and the MX record only shows exchange.mycompany.com? The address remote.mycomany.com is not located anywhere in the zone file.
What I'm trying to do (at least for now) is figure out how to deliver mail to the Exchange server from my software. For example, if I build an SMTP server and a client which connects to my that SMTP server and I want to send an email to webmaster@mycompany.com (where the SMTP server for mycompany.com is hosted on the Exchange server), how would the SMTP server I created connect to the Exchange server in order to deliver the email? Doesn't the Exchange server have to allow some sort of connection from outside the intranet in order to receive emails from other domains (gmail, yahoo, etc.)?

You just have to do a chmod to some file that the script is checking permissions on. Should be a simple fix, I'm guessing the script is also telling you which file is configured wrong.

I currently use a couple of virtual servers for a variety of things e.g. source control, websites, general storage etc.
I am thinking of maybe moving the websites across to Azure as you get an allowance with a MSDN subscription, and this would allow me to probably dump one of the VS's.
I'm just not sure though. Is anyone here using Azure for small personal websites? how have you found it?
(I am not talking about a virtual machine on azure, I am talking about a pure web site)
Edit: After much reading and reasearching, I have completely gone off the idea of using Azure for VMs at the moment. I'm just going to stick to a rented VM from my isp for the time being.

Why have you chosen against Azure? I'm in a similar predicament, would like to know what your considerations were.

Hi,
The first consideration was machine spec. You get a far lower spec machine for the same money on azure versus rented VMs.
The second consideration was bandwidth costs. Again, pay for what you use versus unlimited.
With prices changing every few months, this may eventually swing the other way, but at present i'm afraid for my needs, my current non-azure option is more favourable. (I currently use 1and1
virtual private server (windows) https://www.1and1.co.uk/virtual-server?__lf=Static&linkId=hd.subnav.virtual-private-servers[^])
Cheers,

Hi,
I want to know what's best solution for Windows Server protection with average 50 workstation?
I want to have managed solution to deploy and manage all clients from the server keep in mind that some clients are windows where some some are linux.
What do you recommend?
|
|
|
|
|
Not a recommendation per se; I'm using Avast[^]! on both the Windows and Linux-machines, and seems like there's a "mobile" version. There's a version for "small business", aiming at 1-200 pc's.
The reason I'm not using Symantec is because they provide a backdoor to a third party. Norton has been tried and removed, after coming up with annoying messages, dialogs and eating away resources.
There's a nice comparison on the Wikipedia[^].

There are many managed solutions available. E.g.:
1. Sophos End point security and control
2. TrendMicro OfficeScan
3. McAfee VirusScan Enterprise
However, the best solution depends on your needs!
Some variables could be:
1. Support/ SLA
2. Price
3. Configuration/Management options
4. Integration with existing infrastructure
5. Confidentiality requirements (e.g. connecting to Vendor's servers is not acceptable)
See the following web-sites to get a feel of performance of various AV products.

Depends which versions of Windows Servers you're running?
Forefront endpoint protection and System Center Endpoint Protection come with most licensing agreements with current Windows products.
As was pointed out:
TrendMicro is fairly good, which even MalwareBytes has a Enterprise version of their quality AV.
Manageability is a huge factor though, which cost is not far behind. A lot depends on existing Infrastructure like if you have a Firewall, IDS/IPS systems like Dell Secureworks, or other security blocks in place.

That would be something that youtube knows and we don't. Site configurations are unique to a given site and won't be public knowledge.

Hi coded people, I consider my self privileged to be in your mist today. Please I need a sound and good programmer to make me an SMS platform(gateway?) that will not charge me a dime to send unlimited SMS each time I use it, but a one-off payment or annual or monthly moderate billing will be okay. This platform will have to be something like textmark.com, but much smaller with a maximum of 8 users. Please anyone with recommendations, suggestion, or interest should reach me here or email:itsmytime7@yahoo.com or asylicnet@gmail.com or phone +2348188404908
Please note that i have no knowledge of programming whatsoever

I have a Linux box I use for a firewall with iptables, and I need to put my mail server on the right ip address for proper reverse DNS Lookup.
So I can take inbound packets and NAT them to the mail server, but I need to take outbound packets from the mail server, and send them on a different IP address. The IPTables sends everything out on the same IP, which is 1, but I need 5.
I thinking maybe I could add another gateway, using route, below is my main route, I'd like to add 192.168.3.5 to use a gateway of 69.199.126.198,
Am I on the right track here?, I could use some help on this
/sbin/route add default gw 69.199.126.193 dev eth0
/sbin/route add -net 192.168.3.0 netmask 255.255.255.0 gw 192.168.3.1 dev eth1

I had 2 addresses bound to the mail server adapter, and was only SNAT 1 of them, so I added a SNAT to the other address, and now the mail server responds on the correct ip address for reverse dns and resolves correctly.
So I didn't need a 2nd gateway address, or need to add any additional routing, turned out to be pretty easy. Only took me years to figure out.

try to copy the first ip to your pc and try again should be solved

I want to take all new smtp packets generated inside the network, and send them out on a different ip address, and not the gateway address, so the ipaddress reverses back to the correct ptr record, indicating it's a mail a server that belongs to my domain.
Right now, the packets go out on the gateway, with a different reverse ptr record.
