Added a new WIN7PRO unit to five-system XP network. On one of the XPs I tried to map THE drive of win7 c-drive to use that drive from the XP, but I get "access is denied". I need access to the root directory as well as application directories. I have disabled HOME GROUP on the WIN7. All systems specify the same name for a WORKGROUP, but I don't ever refer to workgroups. I'm OK with a fixed setting via TOOLS/MAP A NETWORK DRIVE or a batch file at boot time that will NET USE the WIN7 system. I am the sole user of these systems, so security is not an issue.
