Error loading Renci.SshNet on Windows Server 2019

[rmbolger]

After installing a recent Windows Server 2019 update, KB4512534 (August 17th, 2019), Posh-IBCLI functions have started throwing errors related to loading the .NET SSH library Posh-SSH depends on, Renci.SshNet.

The following issue goes into detail about the problem: darkoperator/Posh-SSH/issues/284

Apparently the Windows update installed a conflicting version of the library into the GAC which PowerShell tries to load instead of the copy included with the module. The following options are currently available to fix this:

• Uninstall the hotfix
• Manually remove the bad version of the library from the GAC
• Modify your local copy of Posh-SSH to rename the DLL and its reference in the module's PSD1 file. (This is my preferred solution until an official fix is released)
