Exchange 2010 Event ID 1002

I'm in the middle of migrating to Exchange 2010 from Exchange 2003. During installation, the mailbox role failed with this error:

Error:

When looking at the error, the install is trying to go through the network and access the scripts from C$. This is strange since I ran the install from the local hard drive.

After a lot of searching it seems to me as though Microsoft put a lot of protection on the C$ share. No matter what I did I was unable to connect to the C$ share.

What I ended up doing was installing Exchange 2010 to my D drive where the D$ share worked with no problem.

While this is not the best fix (what happens if you don't have an extra partition?), I was able to get it installed and continue with my migration.

If anyone has come across this before or knows the fix to allow C$ to be accessed through the network, please post.

****UPDATE JUNE 26th 2012****
I found out how to make C$ accessible from the network and from the computer. Open your network connections and go the to the TCP/IP Settings (IPv4). Click Properties and then click Advanced. Click the WINS Tab and then select the radio button for "Enable NetBIOS over TCP/IP."

This will require a reboot.
