Access Violation in SNA Manager When Editing DLS Properties

• Microsoft SNA Server versions 3.0, 3.0 Service Pack 1 (SP1) and 3.0 SP2

SYMPTOMS

The Remote Link Services and Alternate Link Services fields of the Distributed Link Service Properties dialog box allow strings longer than 256 characters to be entered. With SNA Server, 3.0 SP1, SNA Manager generates an Access Violation if any of these fields are edited with more than 256 characters. With SNA 3.0 SP2, SNA Manager generates an Access Violation if the "Alternate Link Services" field is edited with more than 256 Characters.

CAUSE

SNA Server uses a 255-character long array to handle those fields but the properties dialog box does not check for the length of the typed string.

STATUS

Microsoft has confirmed this to be a problem in SNA Server versions 3.0, 3.0 SP1, and 3.0 SP2. A supported fix is now available for SNA Server 3.0 SP2, but has not been fully regression tested and should be applied only to systems experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the next Service Pack that contains this fix. Contact Microsoft Technical Support for more information.

MORE INFORMATION

This update adds a check for a maximum length of 3557 characters for both lists. Each list can have a maximum of 127 remote link services.
