Sorry about that. I had originally clicked reply to the wrong message in the
thread. Didn't know if you'd get notified that I had posted something.

I have tried and re-tried all of those things you mention. I can log into
the IIS server as "vdirUser", an account I created to test this whole
process, and simply doing \\remoteserver\share brings up an explorer window
without prompting for a password so I know I have them in synch. Then I
right click in both the root of the share and the subdirectory outlined in my
code and create a new file. It works.

Using that same account to "connect as" in the virtual directory allows for
read-only access. That's when I've changed the authentication settings under
the virtual directories "directory security" tab. I've edited the anonymous
credentials to match the vdirUser rather than the IUSR_machinename account.
I've remove the check box for integrated authentication and I've even tried
"basic" authentication.

I *do* have read, write, and browse permissions enabled when creating the
vdir. "Everyone" as well as the individually named accounts I've tried have
been granted "Full Control" on both the sharing security and the NTFS
permissions on the remote server.

I even added both of the boxes into the domain and tried using the domain
admin account to make the thing work. Still the same ... read only. I'm at
my wits end on this.

Thanks for your assistance,

Bill
