Windows Server 2003 R2 slow in performance

The Windows Server 2003 R2 that was set up last year is running exceedingly slow.

It steadily got slower and now it is terribly slow. Troubleshooting reveals that taskmgr.exe was using approximately about 50% of CPU usage.

After rebooting I observe that explorer.exe used roughly 50% as well and then after one more reboot, services.exe is using roughly 50% as well.

So explorer.exe and services.exe interchange between using the other half of CPU usage, but after a long time only taskmgr.exe is left using 50%.

Extensive research on the internet has not yielded any results yet. In safe mode it works fine and fast with no hitches. Ending services one at a time until all stopped doesn’t make it any faster.

Kaspersky scan did not yield any positive results. A search in the registry for anything unusual couldn't find anything.

Under startup there are only a small number of items and all of them I configured to startup. One forum suggested an update might have caused the problem, so I left Automatic Updates running last night to see if that works.

Any help on this would be greatly appreciated Thanks.

And also, I am aware that I haven't run any anti-malware/spyware programs, this is because: 1. it is too slow to set up anything. 2. I don't think it has malware/spyware,

I could be wrong though, because apart from the sluggishness there is nothing doubtful about it.

The entire programs works fine, registry has nothing abnormal and I have cleaned out temp files etc. with no problem. Please help.

I will provide more info if required to do so. Thanks.

I think you haven't tried doing a defrag on your computer.

Even if you are sure that your computer is free from any viruses or adware or any malware that can make it slow, if you are not doing a defrag on your computer regularly.

The files that are being accessed everyday on that computer will just clutter the hard drive making the access to each file to be slower and slower everyday.

Defragging the computer helps improve the data access by packing all the files making the data access to be accomplished in a lesser time.

Also try checking the hard drive for errors by using any disk utility application that you might have.

Any errors in the file structures of the hard drive, any cross-linked file error that might occur in your system can generate a great decrease in the speed and total performance of the workstation.

You might want to check the computer’s memory if it still can support the number of users that are accessing the server everyday.

If the server has a little RAM memory installed on it and you have a lot of users accessing the server every minute, the server cannot accommodate the number of requests made on all the connections.

Or, if the server is already using the maximum amount of RAM that can be installed in its CPU, you may want to decrease the number of users accessing the server.

The applications that you have installed on the server machine could be one reason as to why it is becoming exceedingly slow, and therefore you will need to check for any memory consuming applications which are not necessary to be on the server and remove them completely.

Another thing you should note that is that the server hosts the information of all the computers on the network, and therefore  day in and day out users and continually adding information on the server.

That means that a lot of space is taken up, and also a large RAM capacity is needed to be able to, make the server run at a higher speed.

So you will need to check the storage space on the server, if it gets filled up, then you will need to upgrade it. Also the RAM will need an upgrade.
