SYMPTOMS
The NetWare redirector component (Nwrdr.sys) of Client Services for NetWare
(CSNW) and Gateway Services for NetWare (GSNW) may send additional
GetNearestServer Service Advertising Protocol (SAP) requests even after
receiving a response to its first request.
CAUSE
NWRDR was originally designed to send a minimum of four SAP requests even
if it received a response to one of the previous requests.
RESOLUTIONTo resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the

After the fix has been applied, there is a new registry parameter that will
set the minimum number of SAP responses Windows NT must receive. This
should be set to the number of servers that will be responding or set to
four, whichever is less.
