You are making a recursive call to DirSize()....I think...

Can you show us the declaration for DirSize as well?

    Public Function DirSize(....?

You may want to check the security settings of the files that are failing. If for instance you are not a local administrator of the machine and you are trying to access 'C:\Documents and Settings\SomeOtherUser' you may run into issues.

I hope this helps :)

I agree with pitster. It should be related to file permissions. Moreover, I suggest you turn off "Simple File Sharing" folder option.
