Symptoms

When you log on to a Citrix XenApp server, running Windows 2003 with Internet Explorer 7, and there are Active Directory Internet Explorer Maintenance Group Policy settings configured, you experience a 20 second delay at logon.

You experience the delay when the stuisrv.exe gui is displaying "Applying Internet Explorer Branding policy…"

Cause

Internet Explorer 7 introduced an error that causes this problem to occur; the error occurs as a result of command line parameters that are parsed by Internet Explorer 7.

Solution:

Enter the following in the open field: rundll32 iedkcs32.dll;Clear.

The following are the commands you can try.

host-is-in-emergency-mode

host-is-in-emergency-mode

Returns true if the host the CLI is talking to is currently in emergency mode, false otherwise. This CLI command works directly on slave hosts even with no master host present.

pool-emergency-transition-to-master

pool-emergency-transition-to-master

Instruct a member XenServer host to become the pool master. This command is only accepted by the XenServer host if it has transitioned to emergency mode, meaning it is a member of a pool whose master has disappeared from the network and could not be contacted for some number of retries.XenServer Administrator’s Guide Command line interface 162

Note that this command may cause the password of the host to reset if it has been modified since joining the pool (see the section called “User commands”).

pool-recover-slaves

pool-recover-slaves

Instruct the pool master to try and reset the master address of all members currently running in emergency mode. This is typically used after pool-emergency-transition-to-master has been used to set one of the members as the new master.

XenServer Pool, Master host failures

November 12, 2009

Master failures Every member of a resource pool contains all the information necessary to take over the role of master if required. When a master node fails, the following sequence of events occurs:

1. The members realize that communication has been lost and each tries to reconnect for sixty seconds.

2. Each member then puts itself into emergency mode, whereby the member XenServer hosts will now accept only the pool-emergency commands (xe pool-emergency-reset-master and xe pool-emergen- cy-transition-to-master). If the master comes back up at this point, it re-establishes communication with its members, the members leave emergency mode, and operation returns to normal.  If the master is really dead, choose one of the members and run the command xe pool-emergency-tran- sition-to-master on it. Once it has become the master, run the command xe pool-recover-slaves and the members will now point to the new master. If you repair or replace the server that was the original master, you can simply bring it up, install the XenServ- er host software, and add it to the pool. Since the XenServer hosts in the pool are enforced to be homoge- neous, there is no real need to make the replaced server the master.
