XCOUNTER FOR NT USER REFERENCE MANUAL 
 
• 
Mac authentication 
Windows NT Print Services for Macintosh do not require Macintosh users to logon to 
the NT machine in order to print, so it is possible for Mac users to impersonate other 
users. To ensure XCounter receives correct login name information, a third party PC 
integration program must be used. Thursby Software Systems Inc. produces a 
program that will facilitate these requirements. 
• 
LPR usernames 
When LPR clients submit print jobs to Windows NT printers using the Microsoft LPD 
service, the username typically shows up as a username followed by the client IP 
address in parentheses, such as username (192.168.1.27). XCounter automatically 
strips off the IP address portion and processes the print job based upon the 
username. 
• 
LPR authentication 
There is no protocol for user authentication using LPR/LPD, so it is possible for LPR 
users to impersonate other users. 
To prevent unknown users from printing, an option can be set in XControl\printer 
configuration for each print queue. 
Networks With Multiple/Trusted Domains 
When XCounter processes a print job, it verifies the existence of the print job owner 
by looking up the name on the designated server in Global Settings - Get User 
Information From (typically the Primary Domain Controller). If the user is not found in 
the current domain, trusted domains will be searched next. 
The print job owner’s home domain is listed along with the username 
(DomainName\UserName) in the first field of the log file. 
To prevent unknown users from printing, an option can be set in XControl\printer 
configuration for each print queue. 
Error Logging 
Any operating errors, such as configuration problems, jobs that cannot be counted, 
etc. will be recorded in the system event log and can be viewed using the Event 
Viewer utility (in the Administrative Tools program group). 
Select Log, Application, and any messages issued by XCounter will be logged. 
Year 2000 Compliance 
XCounter is entirely Year 2000 compliant. All dates have 4 digit year quantities.
