Windows XP Connection Error 678
One of the most common errors we are seeing with Windows XP is the
error 678 - remote computer not responding. First of all don't panic. This message is
basically telling us that the connection profile is not receiving any sort of reply from
our servers. This is for the most part the same thing as an E0040p time out error from Enternet
300 which you may be more familiar with. The same sort of basic troubleshooting applies.
