Unable to access vm by vsphere ou ssh

[next4ideas]

Hi fellas,

Cuple months ago my credentials to access Vm from vSphere was denied (wrong login or password).

i thought that i was hacked but was not.

so i ask data center about the issue and they recommend me to restart all server.

after this reboot, my login works without no issue...

the problem is, i have hosting servers there and each restart i stay 20" offline, so i cant just all the time being restarting server.

so this happen a couple weeks ago and next day i was able to access normal,  now,  today happen again...

its happen with more frequency, and the solution is arbitrary or i should restart the server

do you know what may it happen? if is an vmwarea issue or its a firewall...

thaks advanced

This is not a VMware Virtualization issue . It is mostly related with these things .

1 DNS  

2 DHCP

3 Active Directory.

4.Networking in ESXI (Ping to the Default Gateway of the VLAN)

Please check all these are working with the VM's .  You can do below things to ensure everything works well.

1, Check the VM IP .

2. same ESXI host , connect a VM in same Port group , do a ping test to default gateway of the subnet and check the packet loss (run this in background)

3.nslookup machine name , nslookup ip (check both are resolving proper IP and Hostname)

4.If it is a windows machine , take it remote using mstsc and try to access from remote network , if it is a linux , take ssh access remotely.

5.If any of these are not working , it is related with  (1-4).

you have not specified which user having issue local or ad ? , create a new local user , called as test and check it further if you are observing this .

password lock can happen because of your ad group policy as well
