This article was previously published under Q185691



SYMPTOMS
When SNA Server is configured to use an X.25 connection and configured to use switched virtual circuit (SVC), the link service may stop responding (hang) shortly after initialization. This problem has also been seen on X.25 connections supporting permanent virtual circuits (PVC).



CAUSE
The X.25 link service was incorrectly calling Read Interface Record before setting the link protocol parameters required by the driver.



STATUS
Microsoft has confirmed this to be a problem in SNA Server version 4.0. This problem has been corrected in the latest U.S. Service Pack for SNA Server version 4.0. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
