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. -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx]On Behalf Of Robert K Coffman Jr - Info From Data Corporation Sent: Tuesday, April 27, 2004 11:37 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] The Citrix Server You Have Selected is Not Accepting Connections 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. - Bob Coffman ******************************************************** This week's sponsor - Emergent Online Emergent delivers end-to-end solutions for private and public sector clients.
