I have a WIN7 workstation on our SBS 2008 domain. Lately, I cannot connect to this workstation using either remote desktop connection or remote web workplace. This is recent, perhaps sometime in the last week. I am the system administrator and I have changed no settings. The SBS console shows this computer as offline, but it's not. The user can access all domain resources including shared drives and email. RDC give me "THis computer can't connect to the remote computer." I'm trying that as the domain administrator. Remote web workplace gives me "The computer you are trying to connect to cannot be contacted. Verify that it is turned on, is awake, and is connected to the networl." All these conditions are true. The target WIN7 workstation does have "allow remote connections".

What's up?

Quick question, have you tried connecting via IP instead of name? If not.. try that to eliminate a few possibilities.

Try temporary disabling the firewall on the client and see if you can get in that way.

Also make sure on the computer your trying to connect to that you right-click "My Computer" and go to advanced settings. Click the remote tab, and make sure you have it clicked to allow on there.

Also might want to double check your group policy settings and make sure you part of the appropriate groups.

I would remove the computer from the domain, delete the computer account and rejoin to the domain. (FYI make sure you know the local admin account password before doing so).

I've seen where computers show "offline"and once they say offline it can be a number of things, point I'm going to make is you can troubleshoot for three hours or remove the computer and rejoin back to the network which 99% of the time (in my experience) fixes the problem.

Sorry for the delay, but w/o remote access I have to wait for the user to not be busy.

I've tried disabling the firewall. No go. Workstation is set to remote access. I will next try the unjoin/rejoin idea, but that will not be for a day or two as I'll need some free non-user time. I'll keep y'all posted

WORKS2011: removed the computer from the domain, then put it back. Still "offline". Did the same thing again, but changed the name of the computer. Still "offline."


Pancake_Effect: "Also might want to double check your group policy settings and make sure you part of the appropriate groups."

Group Policy is a BIG labyrinth. Where should I look for this?

btw - did try connecting using the IP, no go.

Other suggestions?

Hi Mark,

There is a likely possibility that windows update installed a Security patch for the RDP which seems to be causing issues. I ran into this on windows 2008 R2 after SP1 was applied.

If you have physical access to this box, verify if it has the two KBs installed.


Security Update for Windows Server 2008 R2 x64 Edition (KB2667402)
http://www.microsoft.com/download/en/details.aspx?id=29169

Security Update for Windows Server 2008 R2 x64 Edition (KB2621440)
http://www.microsoft.com/download/en/details.aspx?id=29116

For additional details what KB needs to be applied for other versions of 2008/7 please refer to this MS bulletin

http://technet.microsoft.com/en-us/security/bulletin/ms12-020

I have physical access to the box, but since I don't have remote access I'll have to wait the office opens on Monday! Thanks for the tip. Meanwhile, I'm thinking about wiping the OS and reinstalling WIN7 from scratch. More recently installed workstations don't have this problem. The only problem with that idea is that this computer came with WIN7 pre-installed and there are no disks! I'll post another question on that since it's not really the same as this thread.

How does your email signature look on mobiles?

Do your employees use mobile devices to reply to emails? With mobile becoming increasingly important to the business world, it is in your best interest to make sure that your email signature looks great across all types of devices.

if this is a dell box then you should be able to get into dell recovery manager and revert to factory image...if not then you may have to contact the vendor to ship the OEM install CD which will probably be with charge associated.

because if you download OS media from MS website and try to apply the OEM license key it will not work.

Getting back to this one ...

bhanukir7 - I've checked the specifi updates you mentioned and they are there. This workstaiton does successfully update via the Windows Server Update Services, and it appears to be all up-to-date.

Nothing I've tried has helped me get to this workstation.

I'll leave this post up a couple of days to see if anyone has any more suggestions. If not, I'll forget about resolution for now.

Thanks

btw - it's an HP box, but I think wiping and restoring the OS is a last resort.

hi

before you think of re-installing the OS try this.

Uninstall KB2667402

powershell wusa /uninstall /kb:2667402 /quiet /forcerestart

and after reboot reinstall KB2667402

This should fix the issue.

Again, sorry for the time delay. Without remote access I have to travel to the neighboring town to work on the actual computer on the weekends.

bhanukir7: tried your suggestion. Still didn't work. The computer wanted to reinstall this update right away. I verified that the update was not installed, and tried the connection. No go. I then verified that the update was re-installed and tried. No go.

I've checked the event log and I am getting a status 23005 error. See image. Does that mean anything to anybody?

event log, remote connection error

Hi Mark,

One way to avoid the round trip to the location would be to install "team viewer" or any other RDP tool that can help you connect remotely for toubleshooting this box.

Check the possible best rdp tool :

http://lifehacker.com/5080121/five-best-remote-desktop-tools

I have used "Team viewer" "logmein" and "VNC" and they would help you avoid the round trip or reduce the overall need for the trip.

Another thing that might be causing this behavior is whether the box is still connected to the SBS domain, Try to disjoin the machine from the domain and join it back and verify.

Please feel free to post back when you have time and i will be watching this thread closely.

regards
Bhanu

Again, apologies for the delay -- still have to physically get to the computer. Currently, the powers that be are not in favor of installing team viewer, etc. Yes, I have used these in the past.

So, any ideas on the 23005 error? It seems that the authorization and resource policies are OK, but what is an error 23005. Here is the actual text:

The user <user>, on client computer, met connection authorization policy and resource authorization policy requirements, but could not be connected to resource "WS01". The following error occurec: "23005".

One web resource says, "Error "23005" means that the TS resource was not found."

I have seen no actual resolutions out there on this error.

I thought I closed this one ... the problem turned out that the computer was not connecting via the hard LAN-line to the domain - the cable connection was actually dead. Rather, it was connecting via wireless to a router on the LAN. That was news to me because I didn't even know this box had a wireless card (no external antenae). The modem was giving the workstation the DHCP address, not the domain server. That messed things up for the remote connection. When I got the LAN cable working the problem went away (I have also since moved the wireless router to the OUTSIDE of the firewall!)

Problem was with DHCP to wireless router rather than to domain server
