Hi Friends, I have a small home network, Vista Laptop -----> D-Link Ethernet Router <-------- XP Home SP2 Laptop On the XP laptop, there is a Western Digital External Hard disk, which I have shared through the home network. The problems I face, The network connection between the home PCs is very intermittent.. It works, and then it doesn't ... No idea why it stops. But once I do a ping -a to the xp laptop, the connections are restored. When I can access the shared drives, copying of files to and fro works fine.. but slow.. However, When I tried to run a program (residing on shared drives), Vista treats me with the blue screen... a crash... Please help... regards raghav..
