When I browse to my own computer's shares by going to \\MYCOMPUTERNAME\ ; I cannot access any of the shares on my LOCAL machine (nor can I access them remotely) and it generates about 40 of the following errors in my system event log:

The following fatal alert was generated: 10. The internal error state is 1203.

Additonal information:

• The process that is generating the error is lsass.exe
• OS: Windows7 Professional x64
• Joined to Domain: Yes
• I was able to access the shares locally in the past
• I am having the same issue on 3 other computers that have similar configurations

Any help would be greatly appreciated, because I have no idea what's wrong. Thanks!
