Being logged out

Hi,

I have set up Eventlog Analyzer on a WinXP Pro workstation and have successfully accessed it from a few other workstations on the network.

My problem is when I log on to it from any workstation other than the one it is installed on I keep getting logged out whenever I try to navigate when I log onto it from the local machine running it it is fine;

For instance I have a laptop setup for testing purposes I can access the web page, log on but when I click on compliance reports or anything else I get logged out.

All Workstations / Laptops have XP Pro SP2, I am currently monitoring an SBS 2003 box and will be adding my 2 other servers into the mix soon.

Thanks
