Creating Certificates for Sealing Management Packs

To create a certificate to seal a managment pack.

1.) Generate a key file –

D:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin>sn -k mykey.snk

Microsoft (R) .NET Framework Strong Name Utility Version 2.0.50727.42
Copyright (c) Microsoft Corporation. All rights reserved.
Key pair written to mykey.snk

2.) Extract Public key from the key file into another file –

D:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin>sn -p mykey.snk outfile
Microsoft (R) .NET Framework Strong Name Utility Version 2.0.50727.42
Copyright (c) Microsoft Corporation. All rights reserved.
Public key written to outfile

3.) Extract the public key token (64 bit hash of the public key) from Public Key –

D:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin>sn -tp outfile
Microsoft (R) .NET Framework Strong Name Utility Version 2.0.50727.42
Copyright (c) Microsoft Corporation. All rights reserved.

Public key is
0024000004800000940000000602000000240000525341310004000001000100ad4e339a2fd­e25 a78de93a363eebbaf755c043fdb44d8ce64a732b0cb24f66cddcbb97bd3966b375d04bef871­d10 c05cbf5213a02ef472feedf4f4855a8a3c5d0116326845d1d2b744b1245d7a24d0ad78d64e0­56911f810e165dd4aed6d05994f2a307a3ecc0a50bd7c5aa16afe123bdd0dc3f9c8aa06d14133f­b9a4cf4f7a2

Public key token is 36c8fd01b281c793

Entity Heath for one or more Management Servers displays Critical in the Operations Manager Console

Here is a great article I found today. This is affecting my management servers.

Problem

The overall Entity Heath for one or more Management Servers displays Critical in the Operations Manager Console. Upon opening the Health Explorer against an affected Management Server, the Monitors affecting the overall Entity Health are either:
Health Service Handle Count Threshold
Or
Health Service Private Bytes Threshold
