After we talked on how to disable logon using command , this post will show on how to disable logon using Citrix Console. Note that :- Users are not able to remote to the server, no RDP, no ICA, nothing. Once logon disabled, users only able access the server via virtualization Console like VMware Client or XenCenter (Virtual server). For physical server, it is either physically sitting before the server, KVM or Remote Access Card (DRAC, or HP iLO) For Command Line , it only can be used locally. I haven't try using PSTOOL yet, but I will update this post whether I can access the server using PSTOOL after logon disabled. For GUI , as we will use Citrix Console, hence it can be done remotely from other Citrix XenApp servers, within the same farm. Hence, if the farm only has one Citrix XenApp server, then you need to get in the box via physically there or virtualization client. Description Disable / enable logon for Citrix XenApp servers via Command Line.
