Setting permissions for XP Pro

I have tried my level best to translate the instructions for setting the folder permissions, which are written for win 2000 , to XP Pro - to no evail.

Could someone help step me through this for XP?

Thanks in advance.

Yeah, I did that, but when I get to step 6, that's where it begins to fall apart for me.

In the properties dialogue box for the folder 'database', under the security tab, I have two entries to start off with and both have been given all but full control. The entries are 'ASP.NET Machine Account ( AG083922\ASPNET )' and 'My Name ( username@domain.com ) ' 

This is where I'm stumped. When trying to view the default.asp page, this is my error.

Error Type:
Microsoft JET Database Engine (0x80004005)
The Microsoft Jet database engine cannot open the file 'C:\forum\admin\database\wwForum.mdb'. It is already opened exclusively by another user, or you need permission to view its data.
/forum/common.asp, line 249

Well, the closest I can find to IUSR_machineName  is IUSR_mypassword.  I typed in IUSR and clicked check names and IUSR_machineName is not in the list, but IUSR_mypassword was.  Nonethless, it didn't work.

Also, I have made sure that simple file sharing is turned off. 

Stumped!

Interesting Note**  Before messing with the permissions, I was able to get the index page to come up.  I then tried to go into admin and ofcourse that is where I got my first 500 error, but after that I can't get the index page back up.

I just did it, but i have a cookie problem, so i don't know if it works :)

I did this:

right click folder -->properties

Sharing tab --> Share this folder

Permissions button --> Add

Then i've pressed advanced, object types and selected groups and users

Find now.

Then somewhere it says IUSR_mymachine

press okay en set allow :)

Dunno if it works, but if it works, let me know please :)

Good Luck
