[Microsoft][ODBC SQL Server Driver]Communication link failure

| I also have started showing strange ODBC link failures on May 4th of 2005.
I'm running asp pages on w2k3 standard server. No known changes have been
made to the system prior to this error.
The initial connection to any of these web pages works great, but if the
refresh or f5 key is pressed, the user is presented with the following error
message:
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC SQL Server Driver]Communication
link failure
/index.asp, line 29
The user must wait about 5-7 seconds before the page can refresh again. It
is almost like a timer has been enabled on my web server. Maybe a windows
patch turned something on recently?
I've also included two snippets from my iis log files:
nc050504.log:192.168.115.155 - - [04/May/2005:14:53:49 -0500] "GET
/about/s_thomp.asp?|11|80004005|[Microsoft]& #91;ODBC_SQL_Server_
Driver]Communication
_link_failure HTTP/1.1" 500 533
nc050506.log:192.168.115.152 - - [06/May/2005:09:33:38 -0500] "GET
/reports/reports.asp?|11|80004005|[Microsoft]& #91;ODBC_SQL_Server_
Driver]Communication
_link_failure HTTP/1.1" 500 535

| Update to my situtation, restarting the server does not fix this problem, but
manually restarting the mssqlserver service does fix it. This can be
replicated.
After looking back at the logs, there was one change, personal monitor
software for an new APC UPS unit was installed 30 minutes before this issue
began to show up in the web logs. I've uninstalled this software and the
problem still exists.
