Directory Services for NetWare (DSMN) fails intermittently, generating the following Dr. Watson error:
The application swsvc.exe has generated an application error.The following message is also written to the System Event Log:
Event ID: 4097: The application, exe\swsvc.dbg, generated an application error. The exception is c0000005 at address 77a056e1 (wcsicmp).
The DSMN service will fail periodically when attempting to rename an account (user, or local or a global group). For example, it fails when the pszOldAcctName is set to a null value and Windows NT attempts to dereference this Null pointer in the _wcsicmp() routine. There are several conditions in the SwpRenameAccount() routine where the pszOldAcctName string can be set to a Null value; however, Windows NT never tests this string before making a call to _wcsicmp() routine.
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or the individual software update. For information on obtaining the latest service pack, please go to:
Microsoft has confirmed that this is a problem in Windows NT version 4.0. This problem was first corrected in Windows NT version 4.0 Service Pack 5.
