Question on VBScript connection issue and SQL 2005

I have a script that performs a number of reiterative tasks very quickly on a SQL database. After a few thousand requests (2-3 minutes) I get the following error:

Error: [Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied.
Code: 80004005
Source: Microsoft OLE DB Provider for ODBC Drivers

The connection string looks like:

Driver={SQL Server};Server=45.22.11.33;Uid=test;Pwd=test;Database=Test

I have changed nothing and it always does this. It doesn't matter if in my script I open and close the connection on every request or leave it open the whole time.

Additionally, the script and the database are on the same machine.

Thanks for any help.There might be various reasons for this. How many concurrent user connections are made in your case? Are you sure you're not exceeding the limit per your license?|||

Is it possible that the IP address on the target machine was changed for some reasons? Can you try the following things?

1) ping 45.22.11.33.

2) telnet 45.22.11.33 1433

If any of this failed, you may have some network issue. Thanks.
