Remote Desktop Connection failing

About a week ago (give or take), my Prevx software switched over to Webroot.  I honestly don't know what changes were made, but I DO know that some were.

 

Round about the same time, my Remote Desktop Connection to another system stopped working.  When trying to connect from my WinXP machine to my Win7 machine, I started getting the following error:

 

An authentication error has occurred (Code: 0x507).

 

Anyone know what might have happened?  My next step is to reload a restore point of a couple weeks back, but I'd like to avoid this if there's a simple fix.

 

Thanks for any help.

Re: Remote Desktop Connection failing

Easiest way to see if its Webroot causing the issue would be to shut it down for a minute while you try to connect to it. If it works then we can do some checks. If it still doesnt work then its most likely another reason why its failing. Without diagnostic logs or Keycode I cant give more info. Try shutting down WSA for a minute and try connecting.

 

Part 1: Turn off Webroot SecureAnywhere

1.    Locate the SecureAnywhere icon in your system tray.  
2.    Right-click the system tray icon and select "Shut down protection."
3.    A prompt confirming whether you want to shut down appears.  Click Yes.
4.    Depending on your settings, you may have to complete a CAPTCHA for confirmation as well.
5.    Once Webroot is shut down, attempt to connect to your PC.

 

Thanks,

Hello enchant and welcome to the Webroot Community!

 

While I was not a user of Prevx, nor do I use Remote Desktop Connection, it sounds like it might be a firewall issue.  

 

Try this.  Open the WSA software.  Click PC Security tab at the top.  In there, click Firewall tab on the left side.  At the bottom, click View Applications.

 

Go over the applications listed to see if the Remote Desktop is listed, and make sure it is not set to block.

 

Somehow I do not think this will work, but it is worth a try.  You might want to submit a trouble ticket for this.  The link for this is below in my signature.

 

 

Related to this, I would also try to remove and reinstall WSA, however I am not sure of the best way to do this for Prevx users.  I am not positive on this, but I think you should be able to remove and reinstall by doing the following:

 

Open the WSA software.  Click My Account tab at the top, far right.  In here, locate your key code, you will need it.  Use the Copy To Clipboard link and then paste the key code into a text file so that you have it saved.

 

Unintsall WSA.  Download the new version using the PC Download link below in my signature area.  Run the installer and use the key code we copied above to activate.  This might help... you might want to get the Remote Connetion going while WSA in removed, and then install WSA while the Remote connection is still going and logged in.  

 

Let me know if any of this is helpful!

Re: Remote Desktop Connection failing

I use WinXP to Win7 Remote Desktop every day and both machines are running WSA, so it should not be the problem. Did you change any settings on the Win7 side in relation to security.

 

I've seen this particular error before in relation to a feature that is present on Win7, but not on WinXP which caused the error to appear in this case. This however should be fixed in Service Pack 3 of XP.

 

Can you test with a different user to log in to your Win 7 to see if this is for all users or just that particular one?

Re: Remote Desktop Connection failing

I shut down WSA, but that didn't make a difference.  DavidP, I checked, and I think that the process is mstsc.exe.  That was listed in the application list as not blocked.

 

My concern is that WSA isn't actively blocking the connection, but that it might have recently made a change to my system settings that could be causing it.  I know that immediately after I noticed it was running on my system, I started getting alert notices that I'd previously disabled.  I've disabled them again.

 

All that said, I really have no hard evidence that WSA is the culprit.  I only know that Remote Desktop Connection has been working without a hitch for a few years till last week.

The Win7 machine is just a simple HTPC.  I haven't made any changes to it in quite a while, unless something automated happened, like Firefox or Flash updating itself.

Yes, I tried that, but no change, sadly.

 

Sorry, haven't figured out how this forum software handles quoting.

Re: Remote Desktop Connection failing

Since no user can connect,  I suggest that you check the following on your Window XP machine: http://community.spiceworks.com/how_to/show/24692-enable-network-level-authentication-nla-in-windows...

 

Please note point 3 of the link if you are not comfortable with using the Registry editor then please don't execute these steps. In that case I suggest you look for someone who is comfortable with using the Registry editor to do this for you.

Re: Remote Desktop Connection failing

Thanks Johan,

 

credssp.dll was already listed there, so I didn't make any changes.

 

I'd have to think that a refusal such as this would be coming from the destination machine, and WSA probably has nothing to do with anything.  I'm going see if I can restore to a previous point on that machine.  Since I never make any changes to it, it shouldn't be much of an issue.

Please let us know if you were able to resolve it with the rollback of the restore point.

Hey Enchant and welcome to the community Smiley Happy

 

The answer itself is in your first post - the authentication error message with the code 0x507. This is a common error across some specific Windows versions and can be fixed with a few registry changes from the blogpost below.

Please let us know how you get on with this.

 

Thanks!
