Moved some code from RxNetWkstaGetInfo to RxpWkstaGetOldInfo, so it

|
|
can be shared by RxNetWkstaUserEnum.

Routine Description:
|
||
|
|
|
||
|
|
RxpWkstaGetOldInfo does a WkstaGetInfo to a downlevel server for an
|
||
|
|
old info level.
|
||
|
|
|
||
|
|
Arguments:

||
|
|
|
||

|
(Same as NetWkstaGetInfo, except UncServerName must not be null, and
|
||
|
|
must not refer to the local computer.)
|
||
|
|
|
||
|
|
Return Value:
|
||
|
|
|
||
|
|
(Same as NetWkstaGetInfo.)
