Our application server has become very slow.
It is a HP Proliant with 4gb RAM and a 500GB hard drive, running Windows Server 2003.
It hosts our intranet software, our financial app and two other client/server applications.
I don't know if the slow performance is due to the workload. Can someone please tell me what the minimum configuration for a server with such a workload is? Also, do I need to get separate servers for the various enterprise applications?
Thanks.

How many Workstations are accessing this server? That is sort of important.

But first off check the Network Traffic. If there is a lot of it this will appear to slow the server down when all that is in fact happening is that the Network is bogged down and causing prolonged lags to occur.

You can use something like Wire Shark to do this

Also check for all sorts of infections including Malware on the workstations. ;)

Thanks for your reply. I have downloaded WireShark and will try it out.
We have 25 workstations constantly accessing the server, and it gets pretty slow after a while.
I also noticed a conficker infection on two workstations, and it keeps recurring. Could that be the problem? Can you give me any tips o how to get rid of the worm completely?

You need to find out where the reinfections are coming from to begin with.

Use Wireshark to check the Network Traffic and if one Station has a lot of traffic that isn't warranted by that user that would be my starting point.

Here I would start out disconnecting the Workstation from the LAM and cleaning it. After you are positive it is clean reconnect it and if the infection reacquires you need to clean the entire LAN.

You should also check that/those end users to make sure that they are not doing something that causes the infection to reoccur. Unfortunately if the Infection is occurring from within the LAN things get difficult and time consuming. But you basically need to clean the entire LAN one system at a time with all Workstations remaining disconnected till you are certain that the entire LAN is clean. ;)

Thanks a lot. I'll follow your suggestions. Just one more question; can you recommend any particular antivirus or malware removal tool to deal with the conficker thing?
Anyone that you feel is particularly effective against conficker itself. I'm currently using ESET Nod32 Business Edition, and even though it notices and cleans the virus, it doesn't seem to be able to get to the root of the virus issue.
