• When connecting to the Process Integration (PI) or Process Orchestration (PO) Integration Builder tools you get the error "Cannot connect to server using message server".

• A restart of the system will usually resolve this but it will reoccur at a later time/date
• The full error is:

• When checking the dev_icm trace file you see an entry similar to below generated around the same time as the logon attempt:
