A client of mine called me on friday stating that she is now unable to view certain websites correctly. I connected to her machine and found that she can view search results fine via google however when she selects a site i.e. "bbc" and the page loads its as if something is blocking the content (see below image). The issue seems to be network wide as the results are the same via the sbs server. I have tried a multiple browsers  as well as restarting the server which did not help, i also flushed the dns cache on the sever which made no difference.

Any ideas?

Since it is network wide and multiple browsers, i'd strongly suspect a network edge issue such as a router, UTM, or proxy.

Thats what i am thinking, strange thing is that its not all websites. I have rebooted the router however it made no difference

For troubleshooting, I'd probably start by watching the HTTP traffic and see if requests are failing and why. Something like IE developer tools, HTTPWatch, or firebug can do that. From there, wireshark can be used to better follow the traffic flow.

Sorry Cliff i did not see your earlier post, downloading HTTPWatch now. Is this best run from the server or client?

Thanks Cliff, just downloading now. What i noticed is that sites that have never been visited previously open fine such as httpwatch however it appears to be an issue with previously visited sites such as the bbc.

Commented:
ok i have downloaded and installed httpwatch and saved a log file by recreating the steps taken. Shall i upload the log here?

Author

Commented:
Its definitely only an issue with previously visited site, i have just checked several new sites on both the server & client and they both open fine. I flushed the DNS cache on the server, is there anything else i could try?

The page in your screen shot looks as if there is a compatibility problem between browser and webpage coding.
If this started recently, run a System Restore.
In IE you could try Compatibility View .  IE Tools|Compatibility View Settings|enter website URL.

The client is using a DrayTek 2830 as their router, i have rebooted the device which made no difference. I have several clients with the same router and never seen an issue like this before. If the problem is at the network edge any ideas on how i can diagnose further.

Does it make any difference if https site or http site?

Issue was with the ISP, client had not paid their bill & the ISP put a block on web traffic.
