SYMPTOMS
When a remote procedure call (RPC) tries to determine the size of the LPWSTR variable in the DHCP_Subnet_Info structure on your Windows NT DHCP server, DHCPSSVC.DLL causes an Access Violation.



CAUSE
The pointers for the NetBiosName and HostName strings point to random memory addresses.

Due to a problem in DHCPSSVC.DLL the NetBiosName and HostName strings are not initialized to NULL, even though they appear to be NULL in the SubNet information subkey of the Windows NT Registry.



RESOLUTION
To correct this problem, 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 has been corrected in the latest U.S. Service Pack for Windows NT version 3.51. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
