Hi Michel,
Remapped drives aren't that hard to handle once you know that volume drive
letters are defined by the DosDevices entries under HKLM\System\MountedDevices.
The Citrix article cloning article mentions the IMA and XTE service entries but
conveniently forgets that the DCOM and ICA listener ACLs use the user SID
including Mchine SID. So basically all the ctx_smauser ACL stuff gets hosed as
well as the ctx_configsvr. If you follow the instructions, you'll end up with a
broken server.
I'm in the process of getting some scripting together using dcomperm and
tsconsec to automate the whole post-clone process for PS4, plus a bit of extra
scripting to fix a few minor places where PS4 fails to update the new server
name (like the XTE/IMA settings and a bit of printer stuff etc). It's
unfortunately not nearly as simple as Metaframe XP was.
The alternative is using mfcfg to fix the ICA listener ACL (remove unknown SD
and add ctx_smauser) and dcomcnfg to fix the ctx_smauser and ctx_configsvr DCOM
ACLs. Search the Citrix knowledgebase for ctx_smauser and use the DCOM ACL
instructions in the document that describes how to recreate the sma_ctxuser as
a guide.
If you've got to clone PS4 the easiest path to make sure things work is to
uninstall PS4 and reinstall after cloning. Of course if you upgraded to PS4
from XP and you've got 100+ applications installed, then it's it's an easy
choice as to whether you rebuild or clone :-(

Hi Angela,
I know it's tempting to clone a server however it's not recommended as far as
I'm concerned. There's always some setting that you didn't take into account
that will cause conflicts. The time saved with cloning will be lost in
troubleshooting weird problems afterwards.
If you do want to go ahead with it, make sure that your server drives are not
remapped, depending on your version of Ghost, this could leave you with an
inaccessable server.
Citrix also has a document up on server cloning. The docuement pertains to CPS4
but contains enoug info to get you going:
http://support.citrix.com/article/CTX107406&searchID=-1
Good luck!
Regards,
Michel Roth.

Hi
I need to build a new server to add to my Citrix farm. I dont want to
manually build this. I have a ghost image of an existing system that I
want
to use for a new server. All hardware is the same. The Ghost image
contains:
Windows 2000 Std SP4
Metaframe XP 1.0
Server is in domain
Server is in Citrix farm
Lots of apps
Image is not SYSPREPed. Its a straight Ghost. Applications are not
name
specific.
Do I simply do the following to get this new server up and running:
- remove server from domain
- rename server to new name
- Change SID
- change IP
Do I need to uninstall/reinstall Metaframe? Will this server be
reliable?
Ive seen documents that explain how to create a ghost SYSPREP image but
not
a document for me scenario (ie existing std ghost image)
Thanks
