Alternate domain credentials / blank password

[bobsensor]

I'm tring to setup Alternate domain credentials to access remote workgroups.

The users on the domain workgroups are: administrator and blank password.

When I add Alternate domain credentials, I enter .\administrator and click ok because the password is blank. I get a message that I cannot enter blank passwords.

I have 50+ workgroupes computers w/ blank passwords. Is there a workaround

thank you

Starting from windows XP it's impossible to log on remotely with a blank password. (local logon works fine)
