Routine Description:
Retrieves statistics from a designated service running at a down-level
server. Currently, the only services recognised are:
SERVER
WORKSTATION
Arguments:
ServerName - Where to run the API
ServiceName - Pointer to string designating service to get stats for
Level - At which to get info. Allowable levels are: 0
Options - Flags. Currently defined bits are:
0 Clear Statistics
1-31 Reserved. MBZ
Buffer - Pointer to pointer to returned buffer containing stats
Return Value:
NET_API_STATUS
Success - NERR_Success
Failure - ERROR_NOT_SUPPORTED
ServiceName was not "WORKSTATION" or "SERVER"
