I am using a HP Proliant DL380 G5 as my host ESX machine (3.5) on which i had a VM with guest as Windows 2003 R2 standard 32 bit edition, i started facing issues just when i configure the Lan setting and had given internet access, and i am sharing a folder with some files on it, whenever the ser ver is idle for some 30 to 40 minutes and if i try to access the shared folder i cannot and igf checked in the console on Vsphere client the gui frezzes and restore only when i reset the VM, I have allocated 2 gb RAM and 1 vCPU to this, Can any one guess what might be the issue, Earlier i was running ESX 4.0 on same Host with same OS with no issues.
