I am currently facing a very troublesome issue, that we have been unable to get to the bottom of.
Our client is running a SBS 2008 Server (fully patched including SP2 for Windows, Sharepoint Services, Exchange, etc.).
About 8 of the 46 clients that are joined to the domain are unable to access http://companyweb
, yet if they go to https://remote.domainname.co.nz:987
they can access the page fine, all the other computers are fine and have no issues.
Attempting to reach http://companyweb
results in the following Internet Explorer error message:
The Page Cannot Be Found (HTTP 400 Bad Request)..
I have run a ipconfig /all on the computers having issues, and they all seem to have the correct settings (all configured to use DHCP from the SBS Server, all picking the SBS Server for DNS and then ADSL router for the gateway), No secondary DNS.
I have run a ipconfig /flushdns on the clients to no effect.
I have run nslookup companyweb and receive what appears to be the correct result:
I am also able to ping companyweb, with a reply from the SBS Server from the machines in question.
I have tried logging on as a different user on these machines and even as the domain administrator account and still have the same problem with http://companyweb
The computers that are having the issue are all various brands of machines (so there is not a common network card driver)and are all running Windows 7 Business Edition.
The firewall on all the PC's in the network is the standard Windows Firewall that has been configured by the default SBS 2008 group policy and the PC's are all running the same Antivirus (NOD32 version 4)
any help or pointers would be greatly appreciated, I am quite sure the problem is with the machines and not the server seeing as so many of the clients do not have the issue but I have been left scratching my head for answers.
