IIS6, Web Sites, Virtual directory and Server.MapPath problems

[itechy]

Okay,

http://wwwhere

to start.

I am running IIS6 on a single IP and using headers to redirect to the correct sites.

I have 2 sites setup:

http://www.abc.co.uk

C:\Web Sites\abc

http://www.xyz.co.uk

c:\Web Sites\xyz

I have created an application for both, don't know whether that is important but I'll put it in anyway.

They both work fine as they are with no problems, but I wish to reference site xyz also like so:

http://www.abc.co.uk/xyz

Again this works fine and IIS6 setups a default application for the Virtual Directory underneath

http://www.abc.co.uk.

The issue is when using the Server.MapPath command to reference a database in C:\Web Sites\xyz when visiting it at

http://www.abc.co.uk/xyz.

Confused yet??

What happends is that by using Server.MapPath("\db.mdb&quot when at

http://www.abc.co.uk/xyz

it returns:
C:\Web Sites\abc

As you can see this is not what I want. I have tried all weird and wonderful combinations still no joy.

Please, please help, I am tearing my hair out

Many Thanks

Tim

PS. If anyone has an easy to understand way of explain virtual paths, let me know
