When a registry hack doesn't work(telnet in Vista)

I guess the telnet issue with vista is well known by all now.

I solved the telnet client issue by a forum that gave me this:

1. Click Start then select Control Panel.

2. Select Programs and Features.

3. Select Turn Windows features on or off.

4. Select the Telnet Client option.

5. Click OK.

6. A dialog box will appear to confirm installation. The telnet command should now be available.

I then attempted to solve the telnet association issue with IE 7 by adding (as instructed by technet) this key to the registry:

REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_DISABLE_TELNET_PROTOCOL]
"iexplore.exe"=dword:00000000


(note the above line can be pasted into notepad and saved with a .reg ext.)

However, this failed to solved my problem. While I can telnet now in vista(I know,I know, it's insecure) I can't click on telnet links and have my default telnet client open. This is a real annoyance and I was wondering if anyone has an alternate solution?

The Telnet URI handler has been removed from IE7

So I think you're out of luck.

There are plenty of folks who claim they got it working. They say the registry hack I posted resolved thier issue but it didn't work for me.

Hi Larry,

Not sure but shouldn't that be 0x00000000

Just a thought? :)

more like 0x00000000 (0)

still doesn't work:(

OK,

Try this tool: http://www.sunrisedoors.com/ie7-telnet-fix.htm

:confused:

Yeah, dude that's the one I tried. if you open that with notepad this is what it looks like:

REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_DISABLE_TELNET_PROTOCOL]
"iexplore.exe"=dword:00000000

Hmmmm,

Don't you need:

"explorer.exe"=dword:00000000

as well?

no

Are you getting any messages and is there anything in the logs?

If you open regedit and navigate to that key, what does it say?
I mean, did the reg file actually add the key? Maybe you need to
edit it manually. At least look to verify that the value is there
and that it is what you expected.

And of course, did you close and reopen your browser?
:cool:

Links like telnet://myhost are handled by the browser by making use of an URI handler. AFAIK IE7 doesn't have this URI handler anymore, hence telnet:// links don't work. If it's possible to add custom URI handlers to IE7 you might be able to add the telnet URI handler.

We have the following:

1. Telnet will work in Vista
2. Telnet won't work in IE7 with the Registry tweak
3. The Registry tweak seems to work for everyone else

That implies corruption.

1. Uninstall and reinstall IE7
2. Re-run the regedit
3. Reboot

No messages in the event veiwer but I do get an "application not found" window(as if the telnet protocol doesn't have a program association) and then when I click ok it says " The protocol specified is invalid"
The registry entry was supposed to take care of that.

OK, I cannot give you a definitive answer as I don't use Vista. You will be somewhat on your own, but perhaps a member with Vista can help.

As I suspected, it looks like either a corruption or synchronisation problem with IE7.

IE takes its file associations from the OS that it is running under. When you loaded Vista and IE7 you did not have Telnet loaded. When you installed Telnet into Vista it created the association (because it works, so it must have done :D) Somehow this does not seem to have passed through to IE7?

No, the way I read that regedit is it simply switches off the Registry block on Telnet which is the IE7 default. We are not even getting that far from how I understand those messages. I agree with your interpretation that they look like a missing association?

I have only played with Vista a few times but you might like to check the entries in Windows Start Menu -> Default Programs. Also try opening IE, going to a Telnet link, right clicking and it will either be "open with" or in "properties" and you should be able to associate.

I am guessing that the application is something like "Telnet.exe" and that will call something like rundll32.exe url.dll which is the Telnet Protocol Handler (or it is in Win 2000:eek:).

Hopefully you will have a checkbox called something like "always open with", or it might just remember it of its own accord?

At worst, now that you have it in Vista, I am pretty confident that a reinstall of IE7 would set up the association correctly.

Good luck!:)

I ama gonna state the obvious here :)

Are you restarting the machine after you edit the registry???

MLF

I have checked all the usual id10T issues.
I just gave up and will cut n paste the links into puTty.

Hmmm,

Did you try a reinstall of IE7 and did you try a different user profile?
