"Cannot find remote computer" error using RemoteApp to Windows 2008 R2 server from XP

I'm trying to run a Remote app in a Windows 2008 R2 server and I gets the "Cannot find remote computer" error.

I can connect using remote desktop, but not to the remote app.

Use remote desktop to connect to the remote computer, but connect with the console session.
arilaniAuthor Commented:
and then what? The problem is not runnig the remote desktop. The problem is running a RemoteApp.
andysappCommented:
So you can't remote desktop into the server? If so, is remote desktop turned on in system properties. (right click my computer and go to properties then move to remote tab). Also, can you ping the server? If not I would suggest to run netdiag and let it check for dns errors.

One important note, I'm trying to login using an adminitrator account and a normal account with the same effect and from the server works fine
arilaniAuthor Commented:
The server works perfect and the remote desktop too.

The problem is with remote app
andysappCommented:
Are these remote apps for the end users to use or are these specific programs for you as an admin for day to day status checks? I am just trying to get the big picture. Is the security set corretly on the folder where the app is installed? shared?
arilaniAuthor Commented:
I'll use for the end users.

I found how to run this. My computer is in other domain. I've tested in the server domain and worked perfect
andysappCommented:
If i understand this correctly. the app is in another domain say domain A and your current domain say domain B works perfectly. The end users in Domain B can't access it? correct? If so, sounds like a permission problem (aka firewall allowing domain B which is on a different subnet access through the lan in domain B). If i missed something in your post. please post back with clarification and i will try to rectify answer.
arilaniAuthor Commented:
Both domains are in the same subnet and tehre is not firewall.

I think it could be the second domain don't see the new server, but I can connect using remote desktop and I can open it with windows explorer
ckershnerCommented:
When you connect to it, are you using the server name or the IP address? I think you might have a DNS issue.
arilaniAuthor Commented:
I connect using the name, What must I check?
ckershnerCommented:
If you are using the name, the DNS and routing is probably working. What kind of App is it? Does it use SQL, Oracle - Web interface? Is it running as a service?
andysappCommented:
I would make sure that your other domain is setup in a seperate zone.

Open DNS management - make sure you have a zone for the 2nd domain, set DC and XPs from the new domain to use the same DNS server and add both domain suffixes to the TCP/IP settings of all machines in both domains or via domain GPO.

I believe that will solve your problem of your desktops not seeing the server with the app installed.
arilaniAuthor Commented:
It is a VB6 application using an Access database.
arilaniAuthor Commented:
I am in a Windows NT 4 domain and the other server is in a Windows 2003 Active DIrectory
ckershnerCommented:
If the correct version of access is on the server and you can get to the application, I would make sure the Access database copied correctly. We have had problems using USB and remote drives causing the access database to loose some information and become unusable.

You have to have RW access to the database with access to run the application at all.
arilaniAuthor Commented:
The problem is not with the application, because it works fine in the server, in the Remote Desktop session and in the Remote App when I connect from the same domain

And the error is connecting to the remote application
ckershnerCommented:
So using remote desktop from the same domain on that server works but using remote desktop from another domain cannot run the application?
andysappCommented:
If ckershner is correct on his assumption. Then you have a dns issue and I recommend following up on my suggestion from above.
arilaniAuthor Commented:
No, it's not that.

Running RD from both domains works fine. Running the Remote App from other domain has the problem.

If it persists, I'll change my PC to the new domain
ckershnerCommented:
Is the domain trusted by the otherone in active directory domains and trusts? If so, you should be able to add your user account from your domain to the security where the application is.
arilaniAuthor Commented:
The domains have are trusted. And I'm running as administrator on the NT domain.
ckershnerCommented:
Is the app on the NT or the 2003 domain? If its on the 2003, is the 2003 still setup to be compatible with the NT domain?
arilaniAuthor Commented:
Is in the 2003 domain. And it is compatible because it works perfect for 2 years

ckershnerCommented:
It would still work, just have problems like this. Goto active directory users and computers, right click on the domain, properties, look at the domain functional level.
arilaniAuthor Commented:
Windows Server 2003
ckershnerCommented:
That is probably the issue. It should be mixed windows 2000. Once you upgrade it (default is mixed), you cannot go back. Moving to the other domain is probably the easiest method unless it is a good time to upgrade the NT to Windows server 2003..
arilaniAuthor Commented:
Ok, I'l take in consideration
ckershnerCommented:
Have a good week...
arilaniAuthor Commented:
thanks, Same for you
arilaniAuthor Commented:
Finally I reinstalled the OS and works fine
