Have the users "hard coded" their usernames \ passwords in the CPN client? Did you force a password reset? That especially would explain it. Are all of the IP's hard coded in the CPN client up and pingable? Not sure if it would cause this error but it's something to verify. _____ Brian Claus, A+, Network+, MCP Network Administrator WESCO Distribution, Inc. 225 West Station Square Drive, Suite 700 Pittsburgh, PA 15219-1122 Phone: 412-454-2412 Fax: 412-454-2540 <mailto:bclaus@xxxxxxxxxxxxx> bclaus@xxxxxxxxxxxxx _____ -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx]On Behalf Of Christopher_Wilson@xxxxxxxxxxxxxx Sent: Thursday, November 20, 2003 11:11 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Urgent: ICA client problem Yesterday, out of the blue, this started happening when logging into the Program Neighborhood client. "The entered credential information is incorrect. Verify that your user name and domain are correct, then type your password.." etc. This stops any app list from being generated. MF 1.8/NT 4 TSE. Client browsing is using TCP/IP + HTTP, looking for the "ica" alias in DNS. Makes no difference if I specify a server name though. The strange thing is that it works through the Nfuse server. Also, there is no error when logging onto a windows client, or Citrix server console. I am struggling to identify where to look on this one. Any help is greatly appreciated.
