This sounds like a limitation or issue on the 2008 server. Your IT person needs to get to work.
The safe mode is a little telling in that some app may be interferring. I've seen expired or near to expired antivirus suites do that. It's well discussed about how to test for that.

I have a perfect internet connection on these Windows 8.1 PC's, I can ping to google.com, I can open up my browser (IE, Firefox, Opera,..), I can search for stuff in google (only in Opera, Firefox)
BUT I can't access any other site. Doing a ping to any other site doesn't work. DNSlookup works. Clicking a result in google doesn't work, I can't open up the site, in all web browsers.
This is weird, because every PC in our room is connected to our Windows Server 2008 R2 SBS and only the Windows 7 PC/laptop their internet work completely without any issues.
Everything is connected through ethernet (1Gbps), I haven't tried Wifi connection yet (no wifi adapter on the w8 pc) But i will, still if anyone knows how to solve this issue, we would be so thankful.
Also the PC's are a custom built W8.1 computer and an MSI all-in-one W8.1 PC. They all have the correct drivers.
Flushing the DNS solved the issue for a brief moment. After a while it would not connect.
But, starting in SAFE MODUS helps, I can connect perfectly.
We took a look at different things, but can't find any solution that works. Only safe modus works for now, so we're pretty sure it's a program that was installed on both PC's or maybe a virus... Oh we did a scan too.
