4155 is the correct version for that patch so should be working. We don't let you remove the server if there are VDIs associated with it so it would need you to remove the VDI from that server before you can remove it.  
Dear all Since a few weeks or months we occasionally have some problems with the heartbeat between our hyper-v servers and the connection broker. The problem happens occasionally on several  or one hyper-v servers. And the effect is that sometimes we are loosing the heartbeat between CB an Hyper-V. The CB reports at this time that the Hyper-V Server is offline. Mostly after the night everything is fine and the CB reports tha the hyper-v Server is online again without any change. Message in the Task View of the Hyper V : Remote computer could not send a heartbeat to the broker. Remote computer could not send a heartbeat to the broker.(42010)  Things that I have already done : - Test Connection and Ports from Hyper-V to the CB (5201,8080 e.t.c.)  -> All succesfully - netstat -aon on CB -> Liste succesfully to appropriate ports  - all Server Firewall are disabled - Checked EventLogs  - restart several times the server "Quest Hyper-V Catalyst"  on Hyper-V Server" - gone through support.software.dell.com/.../58105 we are using in every environement vWorkspace 8.6.1 with actual patches and all involved Servers are Windows Server 2012 R2 with almost recent patches. does anybody have some ideas or any suggestions ? if you need any information just let me know. kind regards Thomas mailto: <ADMIN NOTE: Email id removed per privacy policy>
