Hi,
I am forwarding you this message that I already sent because I didn't understand that joining the Python mailing list is not the same as joining your web site. I am now officially joined in both areas and I would like the following question posted. Btw, I modified the information below by adding the fact that I am using ActiveState Python 2.1 build 210. Thanks very much.
Mike

Subject: Difficulties With win32net APIs
I am running on an NT 4.0 network and am attempting to use some of the win32net APIs to help me manage users, groups, and shares. [Mike Cravitz] I am using ActiveState Python 2.1 build 210. It appears I am being allowed to perform API operations on the local computer (specifying None for computer). But whenever I attempt to specify a computer name - other than None - (even the name of the computer upon which the script is running), I get the following error.
api_error: (2351, 'NetUserEnum', 'This computer name is invalid.')
One example of where this is happening is in a script that looks like this...
import win32net
import win32api
import win32netcon
import string
def listUsersOnComputer( computer ):
loopAgain = 0
retList = []
while 1:
# Get next set of users
entries, total, loopAgain = win32net.NetUserEnum(
computer,
0,
win32netcon.FILTER_NORMAL_ACCOUNT,
loopAgain,
4096
)
# Add this set of users to the return list
for dict in entries:
d = { 'name': str( dict[ 'name' ] ) }
retList = retList + [ d ]
if not loopAgain: return retList
When I invoke this function with the name of the computer upon which the script is running or the name of another server in my NT domain, I get the following traceback...
Traceback (most recent call last):
File "D:\Python21\Pythonwin\pywin\framework\scriptutils.py", line 298, in RunScript
debugger.run(codeObject, __main__.__dict__, start_stepping=0)
File "D:\Python21\Pythonwin\pywin\debugger\__init__.py", line 60, in run
_GetCurrentDebugger().run(cmd, globals,locals, start_stepping)

File "D:\Python21\Pythonwin\pywin\debugger\debugger.py", line 924, in _doexec

File "D:\MyStuff\ListUsersAndGroups.py", line 41, in ?
listUsersOnComputer( 'SYSTEMS_MIKEC' )
File "D:\MyStuff\ListUsersAndGroups.py", line 19, in listUsersOnComputer
4096
api_error: (2351, 'NetUserEnum', 'This computer name is invalid.')
However, If I temporarily change the win32net.NetUserEnum call to specify None, then this works fine. So the temporary change would look like this...
entries, total, loopAgain = win32net.NetUserEnum(
None,
0,
win32netcon.FILTER_NORMAL_ACCOUNT,
loopAgain,
4096
)
Please explain any misunderstandings I might have about how this is supposed to work. Thanks very much.
Mike
