Problem seeing DSN

I have an ASP page written with VBScript which has been tested on my laptop running Personal Web Server.
I have moved the files onto the company intranet, set up the DSN connection on the server the files are located on and tried to run the pages. I get the following error:

Microsoft OLE DB Provider for ODBC Drivers error ‘80004005’

[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

/information/QEV/default.asp, line 16

Anyone got any idea why?
