SYMPTOMS

The Exchange Server message transfer agent (MTA) may stop transferring messages through all X.400 connectors that use a X.25 Winsock stack, even if those connectors are available.

Back to the top

This issue can occur if multiple (two or more) X.25 Winsock stacks are configured and one link is down. When the X.25 Winsock driver returns an error to the MTA listen call, both links may stop transferring data.
