I've never used "UID" and "PASS", but unstead "User ID" and "Password"
Example:
Code:
strConn="Provider=SQLOLEDB; Data Source=<servername>; Initial Catalog=<database name>; User Id=<sql user id>; Password=<sql user password>"
Might be worth a try...
As a side note, don't use "sa" for your web applications. Create a user and give it rights to only what is necessary. Otherwise you leave your entire system open and prone to hacks.
