"List Name From" List Box Shows Only 20 Trusted Domains

• Microsoft Windows NT Server versions 3.5 and 3.51

SYMPTOMS

After establishing more than twenty trust relationships, User Manager and File Manager do not list all the trusted domains. The Add Users and Groups dialog box List Name From list box lists only twenty domains plus the current domain name. Permissions can be successfully assigned by manually typing in the appropriate user account or group from an unlisted trusted domain.

CAUSE

When there are many trusted domains in a network, attempts to enumerate trusted domain names require multiple calls to the LSA API. The LSA API indicates this by returning ERROR_MORE_DATA as a status code to the calling routine. In this case, the calling routine overwrites the returned status code of ERROR_MORE_DATA before it checks the status again to see if additional calls to the LSA API are necessary.

RESOLUTION

To resolve this problem, upgrade to Windows NT Workstation and Server version 4.0.

To correct this problem, upgrade to Windows NT 3.51 (if you have not already done so) and install the latest U.S. Service Pack for Windows NT version 3.51.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 3.51. This problem was corrected in Windows NT Workstation or Server version 4.0.
