We have 2 citrix servers(Xenapp) running on windows server 2008 r2. Starting last Friday 1 server now will not allow you to access the internet. I have went through all the network settings and all are good. I have also compared the network settings with the other server that is working, other than the ip everything else is the same. We have ruled out an IE issue as forefox will nto work either, nor will any software that has update capabilities can update. Any suggestions would be appreciated.
