Hi Bob and SunRay user,
Yesterday on 5th June 2007, the problem comes back. Four of the SR170
users were disconnect from their Windows environment. All the SR1g,
SR150 and SR170 are connected to Cisco 4507 - 10/100/1000 POE blade.
Problem Description:
-----------------------------
SunRay 170 users successfully login to their Windows environment through
Citrix and doing their routine work( MS Word, Excel and IE ). After few
minutes, four (4) of SR170 users desktop hang( cannot type keyboard and
mouse ) and they have been kicked out of Windows environment and have to
re-login from Solaris.
Here are the steps when users login to Windows Environment:
1) Insert smart card.
2) At dtlogin, user type their username and password.
3) Next, reads the user home directory .profile. In the .profile there
is a line executing /usr/lib/ICAClient/wfica
4) Now, user have to enter their Windows username and password.
5) User does their routine work by accessing MS work, Excel, IE and
etc.. After few minutes, their session hang( cannot type keyboard and
click mouse ) and their session kicked out.
6) User have to re-enter their dtlogin username and password.

As was stated earlier, this is most like a problem with your network.
Try running utcapture and seeing what it reports for packet loss... -
