Virtual Host servers constantly being reported as down in OME

Every time a Status poll runs on the vlan that contains all my vmware host servers (I have 26 of them), they are being reported as down, when they are not.

I have increased the timeout in WS-MAN to 60 seconds, but that did not help.

Am running ESXi 5.1 on these host servers and OME 1.1.0.6063 on the management server.

Thank you,
