Querying Windows Sessions

Hi all,

I have posted this question on another channel with little response (http://www.microsoft.com/windowsxp/expertzone/newsgroups/reader.mspx dg=microsoft.public.windowsxp.general&mid=d0a35260-6140-423c-a76f-4831187b0d9a). The problem is that some apps may need to launch processes on remote machines and CreateProcess will return error code 71. Why would that happen, when fsmgmt.msc shows that the 10 sessions limit has not been reached Another question would be - how can I find out which computers have established sessions and is there a WinAPI available

Thanks and best regards,

Calin
