ASP in Vista IIS

Hi,
I just bought a new PC with Windows Vista Home Premium (If I had only known!).
I activated IIS and connected to http://localhost as usual and I got the default iisstart.htm displayed fine. I thought I was incredibly lucky so I copied the files I have on the wwwroot folder on my old PC running on XP (working fine for years) and I got a “HTTP 500” error.
Deactivating the friendly errors I got the following message:
“An error occurred on the server when processing the URL. Please contact the system administrator”
If I rename my default.asp page to default.htm it displays almost correctly (just one picture doesn’t come up other ones are ok, CSS are fine) but then any link will return the same error.
I also tried to create a simple default.asp page with just html code in it and it loads ok.
I’ve tried to look for settings (also in the Norton Firewall) but I can’t find anything relevant.
Does anyone have any suggestions please?
Cheers.

P.S.
Windows Firewall is off.

Hi,
Going through the options in IIS I found a way of getting the real error and it's as follows:
"Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC Microsoft Access Driver] Disk or network error. "

I've looked it up on the Internet and tried to grant all users full access to the Temp folder but with no luck.
I must say that I don't have an IUSR user defined in the user profiles (Vista) though. I'm not sure what I should do now. Should I create an IUSR user?

Can anyone please help now that the error is clearer?
Thanks.

Is the Access MDAC driver installed on your computer? Since W2003 Access drivers have not been included automatically, I don't even know if the Access drivers are supposed to work in Vista.

Hi Dough,
To be honest, I don't know.
Can you please let me know how to check that?
Thanks

Hi Dough,
I think I've cracked it.
It was a problem in the Authentication in IIS (shouldn't use a specific user).
Thanks for your help.

Hi gpt,
I've got exact the same problem. How did you solve this?
I've given IUSR and IIS-IUSRS all the permissions to read/write an access-database(mdb) which is in my inetpub-dir. But still the same error:
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC Microsoft Access-driver] Disk or network error.

Hi all,
I've had the same problem. This might work for you too:

In IIS Manager (Control Panel/Administrative Tools) choose View Application Pools
then choose Set Application Pool Defaults.
Then under Process Model set Identity to LocalSystem.

Good luck, I hope it works for you too.

That worked many thanks!
