Sometime around last Monday, I started getting tons of Access Denied errors when pushing packages that live on UNC shares. The package shares all have "Domain Computers" READ access just like they always have. I ran RSOP.MSC as the LocalSystem account on a few machines, and see nothing in GPO that would deny access.
I get the same thing using PSEXEC, for example
PSEXEC -S -D \\TARGETPC \\SERVER\SHARE\FILE.EXE
But if I use the -C switch to copy the file, it works fine.
If I remote control a managed PC and open a DOS box with MY credentials, and type
net use \\SERVER\SHARE
I get "THE COMMAND COMPLETED SUCCESSFULLY"
If I use LANDesk Remote Control's RUN box to open a DOS box as LocalSystem, and type the same command, I get
"The password is invalid for SERVER\SHARE
Enter the user name for SERVER"
