Error not specified by Microsoft JET Database Engine (0x80004005)

Yesterday from Win2003 to WinXP Pro version, but in the Debug album program, found that the above error, this bug bothers me today for a day, has been unable to find a solution, reload system is not. But the program has a WIN2003 server running normally, search the internet for a while, found that there are many reasons for this, the most common is the following two kinds.

reason
The system temp file has insufficient access rights, always concerned about IIS, the permissions of the file itself, or something,
Most people don't seem to think there is a problem here, before today, I have never thought about it ...

Workaround
Modify the security options for the Temp folder under Windows or Winnt
Plus everyone Full Control
at least write permission to the IIS guest user

But I set it by the two methods. Or did not solve the problem, causing me to reload the system, or not, hehe, depressed.
I know that the reason for this is definitely a permission issue. But I just don't know what the problem is. No solution was found on Microsoft's official MSDN. So I thought, I might as well set the directory permissions for IIS to try, so in IIS to set this site to not allow anonymous access, the result was successful. I am very puzzled, because as a site must allow anonymous access, so I think this is not the normal solution. Only to be settled later ...

There is another: to set the \windows\system32\config\systemprofile\local Settings\Temp directory permissions to everyone's readable permission, the problem finally resolved

Another three things are found:

The first workaround: Use the Tools-> Database utility in MS Access to-> the database to compress and repair the Db/global.asa. If the repair is still an error, please check the DB directory if there are global.dbl files, if you want to delete, if you can not delete the server w3wp.exe process (win2003) or Aspnet_wp.exe process (Win2000) and then delete.

The second workaround:
Set the application pool in Internet Information Services (IIS) Manager, and change the program pool properties for the Web site see the following figure:



to fix the problem.

The third workaround:
In fact, just a few simple steps:
Start ... Run... regsvr32 jscript.dll start ...
Run ... regsvr32 vbscript.dll start ...
Run ... IISReset
