IIS Problem (Urgent)

Hello.  I am perplexed.  We can no longer access any websites on our server (Trend, Intranet, OWA).  When accessing sites externally or internally, we get the HTTP 500 error.  Phones are no longer synching either.  Nothing chaged to my knowledge and all was working flawlessly before.  I have compared all the IIS website settins and NTFS permission to amother server that is working fine.  Any ideas?

denverkeithAuthor Commented:
It is IIS6 (Server 2003 Standard x64).  The error just says "The website cannot display the page..it is under maintenance, or programming error..." HTTP 500.

Nothing in computer managment; even when I try to access OWA.  I thought usually that would log an error.  Our Exchange is working fine and all other systems are going too.  IIS says all the website s are running.  The last updates were installed 12/09 so I cannot blame that.

Is IIS running?

Try doing an IISRESET from the commandline.

Yep it shows running.  I have rebooted and tried restarting IIS.  Still nothing.  I have tracked down the problem to last week when PHP was installed on the server per the webmaster requested.  I only installed and did not do any "linking" or tweaking to IIS.

The http 500 error is generic - to get a more detailed error, turn off friendly http error messages in your browser

Internet Explorer --> tools --> internet options --> advanced tab --> under the browsing section, uncheck 'show friendly http error messages'

Then try access the websites again locally, from the server, and let us know the detailed error message

Are the application pools running?

Might be worth re-applying the latest service pack to your server.  There was an issue a while back with a patch that caused issues with IIS.  The fix was to re-install the service pack.

denverkeithAuthor Commented:
All Application Pools are running.  Its current patch level is SP2 and has been for over a year.  No new updates/changes/patches or programs (other than PHP) have been added since last month.  Are saying reinstall SP2?

Springy555Commented:
If the app pools are running, then re-install of SP2 probably wont fix it.

Can normal html files render ok?  It may be the asp.net engine thats not working correctly.  Could you re-install asp.net 3.5 with the latest service pack?

I thought about that cuase OWA and Trend use ASP, but opur Intranet page is all HTML.  So, nothing displays.  Do you know much about PHP?  I swung all this by the web guy and he sent some links about PHP problems on x64.  I was going to go this route tomorrow.
