Hello: This morning my Citrix farm started giving the following error message: An error of type "IMA" with an Error ID of "0x80000001" was reported by the XML Service at address "http://server:3988";. [Log ID: 5d3e3396] I am running PS 4.0 with Server 2003 w/SP1 and the new hotfix roll-up pack. I have tried to unregister the XML server and re-register but the problem persists. The XML Service port is TCP 3988. Is there anything else that I can try? Thanks in advance. Brian Lich
