Not able to take NE Data backup for all nodes through U2000. Reason is failed to login in the NE, whereas all the nodes are login in on the NMS.
After refreshing the password of “szhw ” user , NE data backup is succeeded.
Reason is NMS take" szhw" and "nesoft" as default user and password for taking NE data backup and customer has changed the password of "szhw"user for all the nodes . So whenever user try to take backup, it failed to login in the NE.
It is difficult to analyze when different client users are there at different location and customer do not predict that somebody has changed the username and password.
So alaways keep a record of NE and NMS username and password.
Also circulate amongst concern whenever there is a change.
