Problem w/ vCards in Outlook 2000

Whenever I attempt to forward a vCard in Outlook 2000, I receive an error dialog that reads ""Can't open file c:\windows\TEMP\contact_name.vcf. The file may not exist, you may not have permission to open it, or it may be open in another program. Right-click the folder that contain the file, and then click Properties to check your permissions for the folder."
I have done the following:
1) Checked to make sure that c:\windows\TEMP actually exists
2) Emptied the TEMP folder.
3) Verified that no other program is attemting to access my contacts.
Any thoughts?
Thanks
Ron
