XP SP2 affecting desktop access through a VPN

When I try to access my desktop at my office through my VPN, if XP SP2 is on, it doesn't goes through. I open Security Center, turn it off and it goes through. What should I do to be able to connect while my XP firewall is on? Thanks in advance.
It sounds like your VPN traffic is being blocked. You should be able to go into Security Center and select "Windows firewall" under "manage security settings." You can then click on the "exceptions" page on the Windows firewall window that loads and select "add port." The port numbers vary based on what kind of VPN you use. IPSec VPNs typically use UDP port 500, and PPTP VPNs use TCP port 3389, so you can try creating exceptions for them. Otherwise, you'll need to contact your network administrator to get that info.
