Cannot initialize "EnquLocktableClient"

Hi,

We are not able to bring up Netweaver Application Server.

Here are the errors we found in defaultTrace_00.9.trc

1. com.sap.engine.frame.core.locking.TechnicalLockException: Cannot initialize "EnquLocktableClient".

2. EncomiHandle.Connect(): connection 1: first connect failed to host sapeis-stg-01 on port 3201 Connection refused (port 3201 to address ::ffff:173.38.0.214 (sapeis-stg-01.cisco.com))()--> Check the status of the enqueue server#

May I know what is the root cause .

We had to move the NFS folder on a new machine and kept the host name same as before.
