VMWare error: Unable to perform the operation. There is no available vRam capacity.

By
Cannot Add or Connect an ESXi Host to vCenter Server
You cannot add an ESXi host to vCenter Server.

Problem
You attempt to add or connect an ESXi host to vCenter Server but the operation is unsuccessful and you receive
the following error message.

"Unable to perform the operation. There is no available vRAM capacity."

Cause 

The vCenter Server system to which you tried to add the host to is licensed with a license key of vCenter Server Essentials that is part of the Essentials Kits. vCenter Server 5.0 Essentials licenses are hard-enforced, you cannot exceed the amount of pooled vRAM for vSphere 5.0 Essentials license keys that are assigned to the ESXi 5.0 hosts while the hosts are managed by vCenter Server. The memory that is configured to the powered-on virtual machines on the host that you try to add or reconnect exceeds the amount of pooled vRAM for vSphere Essentials. For details about vRAM and vRAM pooling, see “Licensing for ESXi 5.0 Hosts,” on page 68.

Solution
Reduce the amount of memory that is configured for the powered-on virtual machines and retry to add or
connect the ESXi host to vCenter Server.

SCCM Unknown computer not able to see Task Sequences after installing Current Branch 1702

By
Soon after installing SCCM CB 1702 we were unable to see Task Sequences deployed to the unknown collection. This issue was identified as a random system taking the GUID of the 'x64 Unknown Computer (x64 Unknown Computer)' record. As a result it was now a known GUID; as we were only deploying Task Sequences to the Unknown collection none were made available. 'x64 Unknown Computer (x64 Unknown Computer)' record 'x86 Unknown Computer (x86 Unknown Computer)' record To get the GUID of your unknown systems open SQL management studio and run the following command: --Sql Command to list the name and GUID for UnknownSystems record data select ItemKey, Name0,SMS_Unique_Identifier0 from UnknownSystem_DISC Using the returned GUID (SMS_Unique_Identifier0) we can find the hostname that has been assigned the 'x64 Unknown Computer (x64 Unknown Computer)' GUID by running the query below. --x64 Unknown Computers select Name0,SMS_Unique_Identifier0,Decommissioned0 from Sys...
