Hi Jorge,

Is there any difference in the browser or operating system used by the final users? This may be affecting the spnego.

Hi All,

In addition you should check in the [PAM|http://service.sap.com/pam] the supported browsers to your system;

For example as per the pam, IE8 of windows7 is supported from 700 SP21.

Thanks

Hi Desiree,

The ADS Server is Windows 2003, our OS Clients are windows7 and the browsers are IE 8.

Testing in our virtual host everything works fine..but in clients under domain landscape some users works others not.

Any clue?

[jorge_velasquez]

The problem is solved, the antivirus was the cause of the issue.

Hi Jorge,

Did you obtain some new traces for this issue? Which is the release and SP of the system? IE8 is not supported for all the releases, as mentioned by Alvaro.

Best regards,

Désiré

Hi Jorge,

I've edited your message so that is is more readable.

Regarding the issue, it is quite strange, specially because it affects just some users. I would suggest to create a diagtool trace of the issue (note 1045019 indicates how to do that). HTTPWatch may help you to verify the header requests.

Also, it would be useful to know if you are connecting through Web Dispatcher, proxies or similar.

Best regards,

Désiré

Hi Desiree,

I used Diagtool for the trace in this post.

I going to use HTTP Watch as you said and also check if there is a wep dispatcher or something.

Regards
