Every 30 minutes, almost by clockwork, a get the following error on my Windows 2008 R2 servers:

Log Name:      System
Source:        MSiSCSI
Event ID:      113
Level:         Warning
Description:
iSCSI discovery via SendTargets failed with error code 0xefff0003 to target portal *10.2.62.3 0003260 B06BDRV\L4SC&PCI_163A14E4&SUBSYS_045F1028&REV_20\5&cabe3b7&0&30050200_0

I have 12 identically built servers connected to this iSCSI network and they are all seeing this issue. I've updated drivers and firmware levels without any change. Any other obvious things I should try before engaging my network team and the vendors.
