I've read the responses that's been provided and tried them with no success. I have a Vista box and would like to run and Access 2007 database, but this database needs to write to c:\. This system is on a domain and it's unknow if a domain policy is keeping this from working. Disabled the UAC and also ran the command "icacls c:\ /(username):(OI)(CI)(M) rebooted and tested to see if files can be written to C:\. No success yet. Any suggestion is appreciated.
