Mavericks: Can't be logged into two servers at the same time?
Update: I had to disable the Guest account on SERVER2. The guest account didn't have access to any shares, but it seems that simply having it active was enough to cause a problem. Here's what I think happened: 1) Log into server1 as "GUEST". 2) Log into server2. OS X must cache network credentials, so tried "GUEST." 3) Server responded with a list of shares, but since GUEST didn't have access, returned permissions error when I tried to open a share. Still seems buggy to me. If anyone has additional insight, feel free to post here.
