As an addition:<br />
<br />
I have rolled back the changes made due to the scvtivesync issue and removed the ports it demand i use, and its made no difference.<br />
<br />
The strange thing is that when i reboot the server, the page loads fine for 10 minutes, but then just stops with the Proxy is busy error.<br />
<br />
Is there any way i can check to see where these concurrent connections are that its having problems with?

Hi i have a SBS 2003 SP2 server running ISA 2000 and IIS 6.<br />
<br />
Everything has been running absolutely fine up until yesterday when all of a sudden, we get the 503 - Proxy Is Busy error when trying to access the default website.<br />
<br />
I have checked in the following Logfiles for any kind of hint as to what may be happening<br />
<br />
%SystemDir%\system32\LogFi<wbr />les\HTTPER<wbr />R\httperrx<wbr />x.log<br />
\W3SVC1\EXxxx.log<br />
%SystemDir%\system32\LogFi<wbr />les\W3SVC4<wbr />\EXxxx.log<wbr /><br />
<br />
I have recently had to apply a fix to the server because ActiveSync had broken because a hotfix caused the server to grab the Exchange push port during boot up, this is now resolved. HOwever a day later this occurred and i can't help wondering if tehre is a butterfly effect here.<br />

503 Proxy Is Busy on IIS6

Small Business Server (SBS) is a line of server operating systems targeted at small businesses by bundling the operating system with a number of other Microsoft products that would normally need to be purchased or licensed separately. The most notable inclusions are Exchange, SQL Server, SharePoint and ISA/TMG (Microsoft's firewall and proxy server).

IIS is Internet Information Services, the web server included with Windows Server operating systems. All current versions are built on a modular architecture; modules can be added or removed individually so that those required for specific functionality are installed. The full installation of IIS includes HTTP, security, content, compression, caching, logging and diagnostics.
