Problem with Shares

[Pilleslife]

Hello,

I've got a problem with the Samba-Share. If I use this with only one client there's no problem, but if I connect with a second. My Windows says: Die Prozeduranzahl liegt außerhalb des erlaubten Bereichs." And in the logfile:

[2010/03/06 21:49:33,  1] ../librpc/ndr/ndr.c:400(ndr_push_error)
  ndr_push_error(5): Bad character conversion
[2010/03/06 21:49:33,  0] rpc_server/srv_pipe.c:2332(api_rpcTNP)
  api_rpcTNP: \srvsvc: SRVSVC_NETSHAREENUMALL failed.
