Unspecified Error

We hit this error about 2 weeks ago on SQL Server 2000 and it seems to be getting worse. 

We have a table that stores phone numbers (wtns).  We have a number of pages that query this table.  I can sit and click a link that queries this table over and over and finally after about 40-50 clicks, it will fail and repeatedly fail for about a minute with:

Microsoft OLE DB Provider for ODBC Drivers error '80004005'
Unspecified error

If our system is busy, I can get to the error much quicker.  The strange thing is this table and these pages have not been modified, some of them haven't been touched in years so these queries worked just fine for that long until Dec 4th when the problems started (nothing significant happened that day or prior to that either).

I have the SQL Profiler running and what I see is the SELECT stmt completes just fine.  The stmt looks as expected and I can even run it manually and it works fine.  Then I see a series of  audit login  audit logout pairs in the profiler but nothing else, where I would expect to see more Queries from that page on other tables.

 If I go to any of the 5 pages or so that has a similar query to this table, I can get the same error.  No other table in our DB causes this problem.  There is no problem cleaning up the connection/resultset either.

 Any ideas where to look?  We've done alot recently to try and fix it:

Reinstalled MDAC, reinstalled SQL Server SP, increased memory, shrunk the trans log, reindexed the table, changed the cursor around (made it readonly as it initally wasn't), modified permissions.  Nothing seems to work. 

This is on SQL Server 2000
MDAC 2.81.1128.0
Windows 2000 SP4
IIS 

Our Connection string looks like the following:

Session("Conn") = "DRIVER={SQL Server};SERVER=DS20021218001;DATABASE=ODB;UID=webUser;PWD=***

Any ideas on where to go next?  What to try?
