Check out CTX127867
Symtoms
1. Unable to telnet to port 1494. Connecting to servername. Could not o=
pen
a connection to host on port 1494: Connect failed.
2. NetStat -a does not show the server listening on port 1494.
3. A Microsoft RDP connection works.
4. Idle sessions are available and the ICA listener is created and enab=
led.
Resolution
1. Run regedt32.
2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services.
3. Create a key named WDICA.
4. Restore a saved key from a working server or manually add the follow=
ing
values:
ErrorControl: REG_DWORD : 0
Start: REG_DWORD : 0x3
Type: REG_DWORD : 0x1
5. Under WDICA, create a subkey named Enum.
6. Restore a saved subkey from a working server or manually add the
following values:
0 : REG_SZ : Root\LEGACY_WDICA\0000
Count : REG_DWORD : 0x1
NextInstance : REG_DWORD : 0x1
7. Reboot the server.
8. Make a Custom ICA Connection to the servers IP address.
If the above steps do not resolve the issue, check for the existence of=
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_WDICA and =
its
subkeys.
If it does not exist, run regedt32 and edit
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\ to include
permissions for Administrators ? Full Control.
Then import the following registry key
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_WDICA]
"NextInstance"=3Ddword:00000001
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_WDICA\000=
0]
"Service"=3D"WDICA"
"Legacy"=3Ddword:00000001
"ConfigFlags"=3Ddword:00000000
"Class"=3D"LegacyDriver"
"ClassGUID"=3D"{8ECC055D-047F-11D1-A537-0000F8753ED1}"
"DeviceDesc"=3D"WDICA"
"Capabilities"=3Ddword:00000000
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_WDICA\000=
0\Control]
"DeviceReference"=3Ddword:8907d030
"ActiveService"=3D"WDICA"
NOTE
The cause for the disappearance or corruption of these registry keys is=
currently unknown.

All,
Here's the scenario, I've got a (Win2k SP2 & MFXP 1.0 SP1) Citrix serve=
r
that doesn't seem to be listening on port 1494. The ICA-tcp listener is=
enabled, but every time I try to connect with Citrix, I get this messag=
e:
"The Citrix Server you have selected is not accepting connections." I c=
an
connect w/ RDP just fine, and all the other Citrix functions (CMC, QFAR=
M,
etc.) work just fine. I have notices a lot of Perflib (1008) and Rasctr=
s
(2001) errors in the Application Log. I also tried to do some Citrix
troubleshooting with the Citrix Enterprise Tracer (ctxstrace501.exe), b=
ut I
could not coerce it into making a log file.
I tried the telnet tests and found that the XML service is listening ju=
st
fine, but Citrix is not. Any ideas?
Here is a snapshot I took of all the active ports on the server:

As you can see, there is no Listener on port 1494. Has anyone seen this=
before? I've spent entirely too long troubleshooting this one server, s=
o
I'm
about ready to throw in the towel & rebuild that box.
