Hi

We are experiencing a strange issue in our VMware environment, We have three esxi 5.5 hosts all managed by a virtual centre appliance which has been running well for some time now

Just recently our backups were failing for any VM that was sitting on host #, after much troubleshooting and diagnosis we found that, from this server (being a physical server, 2008 r2, running veeam, vsphere client) we could not login to host #2 directly using the vsphere client, we get "Call "ServiceInstance.RetrieveContent" for object "ServiceInstance" on Server host2" failed " error, yet any other machine on the network could log directly into this host with no issues at all

the other test was to see if we could download the VMX file of a running VM on that host, again from any other machine we can do this no issues, from this server, connecting to vcentre and browsing the datastore of a VM sitting on host#2 we get "file operation failed"

the strange this is that nothing has really changed, this appeared to literally just stop working. for this host.

The vSphere Client is going away in favour and replacement of the Web Client.....

so....

Any changes to .NET or C# on this computer, with the vSphere Client errors?

Have you installed any new software on this computer recently?

How do you access the ESXi servers? via IP Address, or Hostname ?

Can these be resolved correctly via DNS ?

Can you connect to vCenter Server using the Client?

is it just direct to a server ?

(and for your information, it's quite normal for a change on a computer to break the vSphere Client, we have several computers and laptops, that can no longer be used to access ESXi or vCenter Server)

Also it's not network related, different MTU size on network, jumbo frames mismatch etc

Resolved this issue internally, it was an issue with one host having an incorrect MTU setting on its management network

thank you
