Windows Server 2003 experiences serious performance degradation every day at the exact same time

One of my customer has a Windows Server 2003 R2 SP2 64bit with 16GB of RAM.
They have approx 30 users using  SAP business One, most of them accross the network and a few on remote desktop sessions.
The server performance is fine in the mornings, but deteriorates seriously at 2pm everyday.
We have checked all the usual suspects like the task scheduler, software + anti-virus updates to no avail.
We have also tried to spot any processes in task manager with no result.
We have reviewed employee daily routines to establish if anything specific they do could be the cause with no result.
Does anybody know of any software utilities that we might be able to use to assist us with this problem or does anybody have any suggestions in general ?

check times for automatic windows updates or maybe a backup is misconfigured to run at 2pm instead of 2am??
 
nothing in event viewer/applications or /system at 2pm?

Thank you all for the input.
We have installed Performance Monitor on the server and will switch on monitoring just before 2pm (C.A.T.)  today.
In reply to questions asked :
1) The performance hit is on memory. (The SQL database size is 43GB, the hard drives are SAS and
    the server has dual XEON processors)
2) It's a physical server
3) SQL 2005 SP3 is installed.

We are digesting the other info and will post feedback ASAP

We have been unable to resolve this issue to date. We found many suggestions helpful and implemented many of them, to no avail though. Thank you all for your input.
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.
