SYMPTOMS
========
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).
CAUSE
=====
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.
RESOLUTION
==========
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:
