IE settings going AWOL using Xenapp/RemoteApp published app? here’s maybe why

  Recently came across an issue were some GPO settings weren’t taking when launching published IE instances. Confusingly could launch the published desktop with the same IE instance and the settings would appear to take fine in IE. Issue manifested itself with application timeouts occurring etc, in my instance we had cookies set at medium […]

A timeout (30000 milliseconds) was reached while waiting for a transaction response from the termservice service.

A few posts about this one, can have a variety of fixes – in the instance I came across (environment : xenapp 6.5 servers, bare metal). Seen this issue caused by a xenapp 6.5 to 6.5 farm migration. Post migration systems would hang from time to time, users couldn’t connect via ICA / RDP. A […]

vSphere 6.0 new (well kinda) features – vSphere web client

Not so much a new feature as a definitive improvement for me on its predecessor. Nice write up about it here and articulated my thoughts just as well. http://blog.globalknowledge.com/technology/vmware/quick-look-at-vmware-vsphere-6-0-web-client/ Love in particular moving the recent tasks back down to the bottom of the screen a la old vSphere client and the improved responsiveness (though will […]

vCenter 6.0 new features – enhanced linked mode

From testing in my home lab inadvertently came across this feature. What I didn’t realize prior to installation is it is enabled automatically as long as both vCenter instances are joined to the same vCenter Single Sign-on domain. This helps cuts down the additional config involved in prior releases. More details enclosed:: http://pubs.vmware.com/vsphere-60/index.jsp?topic=%2Fcom.vmware.vsphere.vcenterhost.doc%2FGUID-6ADB06EF-E342-457E-A17B-1EA31C0F6D4B.html Not a game […]

Cluster Resource Pools – remember not to use them as folders!

So recently we came across a performance issue with a bunch of VM’s on one of our clusters. Turns out from doing so much digging that they all shared a common thread, they were part of the same resource pool. The net effect was the VM’s contained were being constrained for CPU over their non-resource […]

Ever need to view VSphere host utilization from a Windows guest VM? Here’s how

A while back got asked by one of the IT folks here if they could interrogate the current health of the host running the VM he was on. As it was a development environment thought maybe fair game. As it turns out it wasn’t too difficult to get the info.
