connectivity issues after SP2

Recently I upgraded a prod db server and since then users are experiencing
connectivity issues. The application errors out with :
Description [DBNETLIB] [ConnectionWrite (send()).] General network error.
Check your network documentation.
They try to ingore the error and sometimes work but not always.
No changes on the application side. The server is 64b Windows Server 2003 EE
with SQL 2005 EE 64b. installed. I upgraded both windows and sql to their SP2
..
I do have a test env. and there everithing went smoothly and no problems
have been reported.
No errors in the logs (both windows and sql server). A warning that network
card driver is outdated (Broadcom 1G). No network issues
The server is usually heavy loaded 8-5 and these issues start early
afternoon and once started happening they dont go away until users are done
for the day.
I am afraid of db corruption and all I can think about is to roll off the
service packs (both windows and sql)
Please help

Can you show us connection string?

No, I doubt it. You would be seeing different symptoms than connectivity
issues.
Have you considered paying attention to the network card driver issue? And
are you sure this isn't a network issue that happens to have started at or
around the same time you installed the service packs? Maybe there is some
process that is now running in the early afternoon that is hogging bandwidth
and making the network unreliable?
