SNMP intermittent timeout on Windows server 2008


I have an SNMP timeout issue on a Windows 2008 server.

Problem statement:
-Snmpwalk timesout locally. This is intermittent (10 polls work and the 11th one times out)
-This is a windows server, so I downloaded the following snmp application to do local tests.
-I believe the default timeout for each object (oid) is 4 seconds. When I set the timeout to 20 seconds, I am able to consistently poll the server (locally) without any timeouts.

Unfortunately, our central monitoring system polls all our servers with a timeout value of 5 seconds. It is very problematic for me to change this, just to address an issue with this one server.

What I tried:
-Restarting the SNMP service
-Re-installing the SNMP service (through the windows features option)
-Rebooting the server
-Installing the Windows SNMP hotfixes that I could find. Although, none of them match the symptoms exactly.

Any insight/help would be appreciated.

Two things are currently known to address the issue:
1)Upgrading the NIC drivers is known to help but not completely resolve the issue.
 2) In the cases we have seen so far, uninstalling anti-virus software has resolved the issue.

Most of these cases involved older anti-virus software versions but we have also seen the issue with current versions that are supported on Windows Server 2008.

While there is not currently a complete resolution, I hope providing this information will help some people identify this issue quickly so they can resolve it and minimize the disruption to their environment.
