If your Server service fails to start and you received Event ID 7023 or 7001, and when you attempt to start it manually you get system error 8 or 234, you may have too many entries in the REG_MULTI_SZ value at: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters\NullSessionPipes

The default information stored in this value is:

                               COMNAP                               COMNODE                               SQL\QUERY                               SPOOLSS                               LLSRPC                               EPMAPPER                               LOCATOR                               

If there are more than 32 KB in that entry, the Server service will fail to start and return the error More data is available, or Not enough storage is available.

The solution is to remove any unnecessary entries from the NullSessionPipes value.
