cannot connect vista to vista.

[Guest breBill]

I'm not sure if this is the right place to ask, so please let me know.

 

We cannot connect from one vista machine to another vista machine using

remote desktop connection. When we try using a domain user account, we ge

the error "No authority could be contacted for authentication." I have

searched quite a bit in vain. It would be helpful if anyone can shine some

light on this problem.

 

These are windows vista enterprise and windows vista ultimate computers

added to our domain. We can connect to the machines using local accounts. I

tried adding the domain user to the administrators account, but that does not

help.

 

I'm not sure what the next troubleshooting step would be, so please suggest

your thoughts.

 

Thank you,

Usually, this error means that you cannot access a DC (Domain Controller)

from your client machine.

Re: cannot connect vista to vista.

 

I agree, but we can sign on to the domain on each of the vista machines. In

fact, we use these machines for developing software. I found that I can get

a remote desktop connection if i add 'enablecredsspsupport:i:0' to the .rdp

file. This makes the inital authentication prompt go away, the connection is

established and then I can sign in. In some cases we still get an error

saying something about Network Authentication being needed prior to making a

connection. It's odd this new error is hit or miss, but we haven't

researched it much. I'm looking into CredSSP for further information. If

you have any further thoughts, I'd be happy to hear them. Thank you for the

response.

Re: cannot connect vista to vista.

 

That's not the recommended way to solve the issue.

 

I think that you'll have to use the syntax "MyDomain\MyUserName"

when trying to connect. Leaving out the "MyDomain" part can cause

the rdp client to try to log you on with a local user account.

Re: cannot connect vista to vista.

 

i do use domain\user for the userid. i actually tried all the different ways

of specifying/not specifying the userid...no combination get's rid of the

error.

 

based on Mr. Kuzin's post before, how can the connection to the domain

controller from the remote desktop connection software be tested/verified?

Re: cannot connect vista to vista.

 

Enable auditing on both clients and check the EventLogs.

If there's a problem contacting a DC, you will see an error or

warning there.
