I've had the opportunity to work in a locked down environment so am fairly familiar with DISA STIGs and the types of settings that are required to be applied to workstations and servers in that environment. I was recently working on a Citrix implementation and ran into a couple of issues caused by these settings. … Continue reading Citrix in a STIGed Environment
DHCP Failover Issue
Ran into this one today when setting up DHCP failover between 2 Windows servers. On the first screen after selecting Setup Failover the Relationship Name field showed up as "169.254.x.x - Actual Server Name". This was on a functional production DHCP server that was also a Domain Controller. 169.254.x.x is an APIPA address so this … Continue reading DHCP Failover Issue
A single user cannot log into a Win10 Citrix Desktop
Scenario - a user who had been working fine can no longer launch a Citrix Win10 non persistent desktop from any client - Windows or Wyse ThinOS, internal or external. No other users affected.

RDS Gateway with Azure MFA
I recently worked on setting up an RDS Gateway with the NPS Extension for Azure MFA for remote access.

The Microsoft Network Device Enrollment Service documentation seems pretty straight forward, but after installing and configuring it I was faced with a couple of different issues that took me way too long to figure out. Hopefully this will save someone some time. Note: I installed this on a server that was an Enterprise CA and … Continue reading NDES Configuration

Windows 10 – What a ride so far!
I've been working a lot with Windows 10 the past year, especially in the VDI context. The new release schedule has been quite a ride so far. The changes between 1511, 1607, 1703 and now 1709 are in and of themselves challenging to keep track of and support in a business environment but then add VDI … Continue reading Windows 10 – What a ride so far!
1 Cluster Node won’t join
After doing maintenance on Cisco UCS Server Profiles I had to fix up network adapters on a 4 node Hyper-V Failover Cluster. After the maintenance 3 of the 4 nodes came online. Errors in the event log included cluster service termination due to file already exists. After checking all settings on the 4th node and doing … Continue reading 1 Cluster Node won’t join
