Dbnetlib connectionopen(preloginhandshake()) error

SQL 2000/SQL 2005(see below) running on Windows 2003 sp1, web server running
IIS 5.0 on Windows 2000 sp4.
Sometime in the first week of every month since at least Nov 2005, I get an
Dbnetlib connectionopen(preloginhandshake()) error. Connections to the
databases from the Web pages will be slow and intermittent. Rebooting both
web server and sql machine does not fix the error.
Upgraded to SQL 2005 in Jan 06. The connection issue will last 24 to 36
hours then fix itself. Any suggestions on how to fix the error would be
appreciated.
Thanks
During that time the system is acting as described, I would run a SQL
profiler trace to rule out SQL Server jobs/users. If not found, then run
Windows performance monitor looking at memory and network traffic.
Let me know where I can help.
