PRB: Firewalls or Proxy Servers Can Cause RDS to Fail

• Microsoft Data Access Components versions 1.5, 2.0, 2.1

SYMPTOMS

Microsoft Remote Data Service for ADO (RDS) fails with different error messages when used in conjunction with some firewalls and proxy servers.

There is no specific error message associated with this problem. RDS returns seemingly random error messages. The errors can occur on Queries or Updates.

CAUSE

RDS requires the firewall or proxy server to pass the data between client and server without modification. Some firewalls or proxy servers may modify the User-Agent tags or other data that RDS needs to function properly.

Currently, the only way to determine if your firewall or proxy server operates properly with RDS is to try to use RDS with and without them.

Due to the number of firewalls and proxy servers on the market today, and the lack of uniform standards, Microsoft cannot verify that RDS operates with every one of them.

Be sure to check this Knowledge Base article often for information about firewalls that do not function well with RDS. As they are discovered, this article will be amended. If you believe your firewall or proxy server does not operate correctly with RDS, please contact Microsoft Developer Support.
