Can you use the vSphere Web Client?

The vSphere Client is old, and no longer really supported, and you cannot edit virtual machines using it (version 10 or later!).

I never used this client.
1 hour ago, the normal client was working.
Now not anymore.

I would recommend testing and getting used to using the Web Client, it's supported, and you can do ALL the functions with it, with vCenter Server.

You can no longer do all the functions with vSphere Client - its now limited.

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

In vSphere 5.5, all new vSphere features are available only through the vSphere Web Client. The traditional vSphere Client will continue to operate, supporting the same feature set as vSphere 5.0, but not exposing any of the new features in vSphere 5.5.

I just changed this and it stopped working:

moved server to another OU

installed the classicshell

Can this harm the vcenter ?

If you use Group Policies to lock down your servers, it's possible, e.g. Firewall ?

Eprs_AdminSystem ArchitectAuthor Commented:

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:

Eprs_AdminSystem ArchitectAuthor Commented:

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
So, are the Group Policies between the different OUs different?

are the following ports open?

22 and 443 ?

Are the vCenter Services started?

for some reason I get messages that IIS is installed and the port 80 is in use.
Is IIS on vcenter recommended ?

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Do you have IIS installed on this server for a reason?

Eprs_AdminSystem ArchitectAuthor Commented:
no I cannot remember

Eprs_AdminSystem ArchitectAuthor Commented:
is installed by default from the vcenter ?
Is needed by vcenter ?

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
It's not installed by vCenter Server on any our installations.

It's not required, vCenter Server does not use IIS.

If you have IIS, it will conflict.

Eprs_AdminSystem ArchitectAuthor Commented:
ok I will uninstall this role, because this machine is just for vcenter

Eprs_AdminSystem ArchitectAuthor Commented:
ok now it is working again.
And with the Webclient I can see more features.
I also have seen the feature VSAN.
I want to use it but it is not possible and they always talk about SSD disk in the hosts.
Are SSD disk necessary ?

Discussions of vSAN are off-topic here.

I believe your question has been answered, if this question has been helpful please assign points.

Please post a new question for help with vSAN, and myself or other experts will be glad to assist.
