Hi everyone, I am currently having a problem that has been troubling me for a long time, I've looked all over the internet and I still haven't found a solution. My problem is that my XP network cannot access my Win7 server, but its not the same problem that has so many solutions around on the internet. Here is my situation: I have 2 networks in my office. Network1 consists of 3 WinXP machines connected via Router1 to Modem1 to the internet. Network2 consists of 7 64-bit Windows7 machines connected via a Switch to Router2 to Modem2 and then to the internet. I also have a server machine running Windows7 64bit with two network cards. One NIC is connected to Router1, the other connected to the Switch. All of the above machines are all under the same work group: WORKGROUP My Windows7 machines on Network2 can interact fine with the server. However, my WinXP machines cannot access the server "most" of the time, I've had a rare few occasions where it magically worked. Can anyone help me out solving this issue? Thanks!
