cannot login ciscopca

Unanswered Question
Feb 17th, 2009


When I try to connect to ciscopca I get the following error:

Unable to contact server. Try logging on again in a few minutes. If the problem persists, contact your Cisco Unity administrator.

I have done some reading I checked the TCP ports with tcpvcon.exe but I can not find anything. I resolve it with a reboot of unity server.

Normally the next day this error reoccurs.

Any thoughts?

This is a demo environment in our lab, but I can hardly propose this or show this to potential customers or the sales depth, nor do I want to unless I find out why I have this error.



I have this problem too.

Hello Brad,

Yes you are right I have an security error:

2009-02-19 10:37:08.994 [Thread-9] ERROR - AvxmlConnector.generateResponse() IOException Server returned HTTP response code: 401 for URL: http://UNITY/Avxml/AvxmlSvr.dll

2009-02-19 10:37:08.994 [Thread-9] WARN - sendEnvelope: no response generated

<?xml version="1.0" encoding="UTF-16"?>">




Connection to the unity server(s) has failed

2009-02-19 10:37:09.291 [Thread-9] ERROR - perform - Attribute "PROVIDER" unknown/unset value: null

2009-02-19 10:37:09.291 [Thread-9] WARN - perform - Attribute "PROVIDER" will be defaulted to: Windows

But the AvXml directory in IIS allows anonymous access.

After a reboot of the unity server I have access for some time.

Is there some more security parameters to look at?

What version of Unity, do you have any Engineering Specials installed?

There have been a few CPCA issues resolved in Engineering Specials. Some require installing an ES and a few post installation requirements.

Brad and Christopher,

Thanks for your replies.

At this moment I am not in the office, so I can not try it.

On Monday I shall do some checking,

I checked all the things that are mentioned in the links and all is OK.

Problem is: It works, the next day it doesn't. After a reboot it works fine for another day.

I am, using Unity 5.0(1)

Maybe I should try some upgrade's?

I am running win2K so I have IIS 5.0 and I don't think Application pools are supported on IIS 5.0

I can run Unity 5 on Win2K? I installed it without problems and I the installation manual says it supports 2K and 2003
