or even better, find the task that is using up all the connections, and fix it! ;-)
Run an activity monitor on the SQL server and see what connections are active.

Question
IIS Loses ADO Connection to MSSQL
I have a Windows 2000 Server running approximately 30 websites and MS SQL Server 7.0. Most of the sites are dynamic and pulling information from the database. Occasionally (once a week or so) I get the following error on all of the sites that access MSSQL:
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]SQL Server does not exist or access denied.
/includes/dbConn.inc, line 6
I know for a fact that the SQL Server does exist. Further, I'm able to access the DB through SQL Query Analyzer, so I don't think the problem is with SQL Server. I put each of these sites in their own memory space by setting "Application Protection" to "High (Isolated)" in IIS, but this doesn't seem to have made any difference.
When I get this error, I've tried restarting the MSSQL service & restarting IIS but neither has made any difference. The only way to fix the problem is rebooting the server, which is annoying as hell. Can anyone give me any guidence on this?
Thanks in advance.

Here's a cute solution in case you can't resolve this problem: how to promptly notice the problem and reboot the server - the idea comes from Russian joke site http://www.anekdot.ru
Put another server with Linux. The 2nd server's only job is to periodically ping the 1st server (in your case, to periodically connect to sql server on the 1st server same way as your websites do). When the next attempt fails, meaning it's the time to reboot 1st server, the monitoring application on the 2nd server ejects CD tray, which pushes the button "reset" on the 1st server.
Sounds like IIS and SQL are on the same box... yes? Assuming that, you should be using a different protocol as vadimrapp1 suggested. In adddition you should use a DSNless connection using OLEDB. Example:
cn.Open "Provider=sqloledb;" & _
"Data Source=servername;" & _
"Initial Catalog=databasename;" & _
"User Id=userid;Password=userpas
Make sure connection pooling is turned on.
Check your client network config using CLICONFG

Most likely, some leak that eventually exhausts some tcp/ip-related resource. Try another protocol, for instance named pipes, or even better, shared memory, instead of tcp/ip.
