It’s missing the firewall rules list.
access-list 102 deny tcp any any eq 2512
access-list 102 deny tcp any any eq 1494
access-list 102 permit tcp any any eq 2598
access-list 102 permit tcp any any eq 80
access-list 102 permit tcp any any eq 1433
access-list 102 permit tcp any any eq 1161
Basically we’re looking at the deny 2512 (IMA) and 1494 (ICA/HDX)

It should be XML I think
XML is for enumeration, but if XA in one zone is without users it will be IMA issue.
You can still use XML enumeration from the zone that working but it will not send the ICA connection to the XA servers with the IMA problem.
There is no IMA on XA7.15 any more
Other questions, however, use the term “ima service”.
