On my home network there are W8-A, W8-B and W7 machines. There is no problem networking among these machines except from W8-A to W7. The shared folders on the W7 are displayed on W8-A but if I attempt to click-open any one of them no ID/PW is asked for and the following message is displayed:
"You do not have permission to access . . . . . Contact your network administrator . . . "
W8-A <--> W8-B OK
W8-B <--> W7 OK
W8-A <-- W7 OK
W8-A --> W7 NG
W8-B and W7 are logged in by the same ID and password, but W8-A is logged in by a different ID and PW.
I can open any folder of the W7 from W8-A *if* W8-A is logged in by the same ID and PW as for W7/W8-B.
I wonder what could be wrong. Any idea?
