Hi Jess,
I guess you should contact the IT administrator at your company because it seems a network setup problem if you can't ping your server from your client workstation. The causes may be many but as I said, I know little about this aspect (network settings).
Sorry I can't help you further there...
Or try Nagarajan's suggestion first: disable anti-virus and firewall. If this solves your problem, you can pinpoint the causes and your IT administrator knows where to start.
Regards,
San
