Symptoms

Resolution

• Stop the K2 Blackpearl server service
• Backup the "K2HostServer.exe.config" file
• Create a directory on the C: drive - "C:Temp"
• Make a copy of the "K2HostServer.exe.config" to "C:Temp" directory
• Rename the K2HostServer.exe.config in the "C:Temp" directory it to "web.config"
• Run Command Prompt in Administrator Mode
• Run 'cd C:WindowsMicrosoft.NETFramework64v4.0.30319' to change directory to this framework version
• Run 'aspnet_regiis.exe -pdf "connectionStrings" "C:Temp"'
• This command will decrypt the encrypted 'connnectionStrings' section

2. In the web.config file search for 'connectionStrings' and in the connectionStrings section search for 'WorkflowServer'

3. Change the Host from the fully qualified name to the PC name:

e.g.

Host=K2server.domain.com to Host=K2server

4. Rename the web.config file to 'K2HostServer.exe.config'

5. Copy the K2HostServer.exe.config to the following directory: 'K2 BlackpearlHost ServerBin'

6. Start the K2 Blackpearl Server Service.
