Guest breBill Posted July 31, 2007 Posted July 31, 2007 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, -------------------- Bill Cochran

Guest breBill Posted July 31, 2007 Posted July 31, 2007 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. -- -------------------- Bill Cochran "Sergey Kuzin[MSFT]" wrote: > Usually, this error means that you cannot access a DC (Domain Controller) > from your client machine. > > -- > This posting is provided "AS IS" with no warranties, and confers no rights. > "breBill" <breBill@discussions.microsoft.com> wrote in message > news:FFA1BBB6-A7FF-4456-A024-F567A75A1A0B@microsoft.com... > > 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.

Guest Vera Noest [MVP] Posted July 31, 2007 Posted July 31, 2007 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.

Guest breBill Posted July 31, 2007 Posted July 31, 2007 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? -- -------------------- Bill Cochran "Vera Noest [MVP]" wrote: > 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.

Guest Vera Noest [MVP] Posted July 31, 2007 Posted July 31, 2007 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. _________________________________________________________ Vera Noest MCSE, CCEA, Microsoft MVP - Terminal Server TS troubleshooting: http://ts.veranoest.net ___ please respond in newsgroup, NOT by private email ___ =?Utf-8?B?YnJlQmlsbA==?= <breBill@discussions.microsoft.com> wrote on 01 aug 2007 in microsoft.public.windows.terminal_services: > 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?
