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?
