Thanks Jim.  I found this document, but symptoms listed don't apply....

We can telnet to 1494 (and see the ICA ICA ICA deal)
Netstat shows server listening on 1494


So far, 4 users are affected.  Why do I get the feeling that more will be
soon???!!

Thanks again-

Bob

CTX127867 - Error: "Cannot Connect to the Citrix Server: The Citrix Server
you have selected is not accepting connections."

This document was published at:
http://support.citrix.com/kb/entry.jspa?externalID=CTX127867


Document ID: CTX127867, Created on: Mar 29, 2002, Updated: Jun 7, 2003

Products: Citrix MetaFrame XP 1.0 for Microsoft Windows 2000

Check Registry for WDICA key

Symtoms

1. Unable to telnet to port 1494. Connecting to servername. Could not open 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 enabled.

Reproducible Steps

1. Run regedt32.

2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WDICA.

3. Save the key.

4. Delete the key.

5. Reboot the server.

6. Make a custom ICA connection to the server IP address.

Resolution

1. Run regedt32.

2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services.

3. Create a key named WDICA.

4. Manually add the following values:

ErrorControl: REG_DWORD : 0

Start: REG_DWORD : 0x3

Type: REG_DWORD : 0x1

5. Reboot the server.

6. During the reboot of the server in step 5, a subkey named Enum will be
created with the following values.

0 : REG_SZ : Root\LEGACY_WDICA\0000

Count : REG_DWORD : 0x1

NextInstance : REG_DWORD : 0x1

7. 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. You may need to add permissions to this key in order to save and
restore the key from a working server. When this key is manually deleted and
the server is rebooted, the key should regenerate itself. If the key does
not automatically regenerate itself, you can restore a copy of this key from
a known good server or manually create the entries. When replacing this key
with a copy of the key from another server it is necessary to navigate to
the following location:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_WDICA\0000\Cont
rol

Delete the data of the following value located within the above referenced
key and then reboot the server:

"DeviceReference"=dword:8188fd10

Upon reboot the data should repopulate.

NOTE: The cause for the disappearance or corruption of these registry keys
is currently unknown.

Pleh, pleh!  said Mr Backward:

Environment is NT4 TSE / MF XPe SP1.  All servers in same farm and same
location.  (Please don't tell me to upgrade, its not like I wouldn't have if
I could!)

Some users are getting the subject error message.  Started yesterday.  Three
of the new MS Patches were applied this past weekend.

The users in question are getting the error message on all apps (ie. it
doesn't just affect certain servers.)

Clients in question all (so far) are running NT 4 locally.

Nothing is logged in event log.  I also tried clearing MSLicensing key on
one client.

Also, I tried logging in from my computer as one of the affected user's, and
it worked??!!

I restarted IMA on each Citrix server, no help.

CPU utilization on these servers is very low (around 10-15% on average.)

I'm at a loss.  It seems like this is either a license problem (citrix
reports 58 free right now and no terminal server license problems are being
logged) or a security issue (but then why does one of the user's IDs work
from my desk?)  Neither scenario seems to fit the facts.

Any help appreciated.
