Definitely in every IT person life there would be a time to remove Antivirus client from servers or client machines. Yes i had also in a situation that have to remove McAfee Antivirus client from one of the Windows 2008 R2 machine.
In our enviornment we are using McAfee EPO Antivirus server (4.5.0) and VSE 8.7 versions. In all machines client agent has been installed and getting regular updates from EPO server.
Removal Process of McAfee Client
First remove McAfee Virus Scan enterprise from control panel.
Once it done try to remove McAfee agnet but it won’t allow you from GUI.
You have to do it the uninstallation from command prompt by using below switch
c:\Program Files\McAfee\Common Framework\frminst.exe /forceuninstall
We are using NetApp Storage box to keep departmental and end user home folder. We have enabled CIFS on Storage and shared to each department with their respective.
Today we have seen that NDMP backup job has failed with error code 99. It was a full backup and have to resolve quickly because it’s contains business data.
When opening the failed job window we could see that below findings.
2/24/2012 9:16:03 AM – Error ndmpagent(pid=9744) ndmp_authenticate_connection: ndmp_connect_client_auth failed 2/24/2012 9:16:03 AM – Error ndmpagent(pid=9744) failed to connect to NDMP server fas2050b, connect error = -1009 (NDMP server login failed – verify attributes with tpautoconf -verify)
It’s clear that Storage team had changed the password of Root account. When we contact them they said yes and we updated the settings with new password
Here is the place we need to change this settings in Netbackup Console.
Once we changed the credentilas triggered a mannual backup of NDMP and it start working fine.
There was a complaint from users that they cannot access data’s which is storing in NetApp CIFS ( NAS). Below error they were getting while accessing the shared folder from NetApp.
We checked the filer and it is up and running. Also we can able to ping to filer from Domain controller and vice versa.
But the below logs were we can see in NetApp console.
Sat Oct 15 05:20:38 GMT : cifs.trace.GSS:error: AUTH: Unable to acquire filer credentials: (0x96c73a25) Filer and domain time differ by more than 5 minutes.
This made me sure that NetApp filer and Active Directory domain controller time is not matching. so we need to go to filer and check the time is exactly correct with AD. Up to 5 minutes is ok to but if it is more than that you need to sync it.
Go to filer view –> Set date and time–> Modify date and time.
After setting the time match with Domain controller we were able to access the CIFS data.
If the clock is not matching then you cannot join the filer in to the domain and cannot setup the CIFS.
