Virtualising anything creates its own small set of issues, as you have just added another OS to maintain and another layer that can misbehave.

 

We had a client call late Wednesday advising their network drives were not accessible.  It appeared the guest OS was unable to communicate with the LAN, even though we were able to communicate with the host OS on the same network card just fine.  A reboot of the host server got the guest back online and we scheduled some time this weekend to work on the issue.  Unfortunately the same issue happened half an hour ago and another quick reboot has got it back online once again.  This is on a server that has been in place for just about a year and has behaved flawlessly until now.

 

Considering computers are just a giant pocket calculator, more than their fair share of witchcraft is required.  Especially if you don't want to 'release the magic smoke' as one of my team amusingly chimes in with occasionally.

 

 

Virtualization does not add issues but you rather save on power, resources and physical space. Event logs is the key to your issues. From the issue you are describing it sounds like you need ot turn off.

Virtualization of a single box doesn't save any of those resources.

What i am saying that 99% of the company that i deal with don't need anything but standard mail features!!

 

I have set them up on a Cloud VM using IMAP accounts and they are happy!!

 

If you take the 500+ email accounts i have got over lots of small business that i look after.

 

Office 365 email @ $6/month * 500 accounts = $36000/year which will give users all these extra features they won't end up using!!

 

I have some customers that use 365 and are happy but its there choice for the extra expense

 

 

 

 

With IMAP you lose the ability for syncing of contacts, calendars, tasks sync. Syncing a mailbox over 1GB on IMAP shows how painfully slow it is. Autodiscover on Exchange rather entering the IMAP server settings manually. Try that for 500+ email accounts now and your support costs will justify the business requirements and costs. Office 365 has plans starting from NZ$2.50/month btw.

 

Just look at when was the last time IMAP protocol was updated and then look at how often does the Office 365/Exchange/Active Sync protocol gets updated.





Do whatever you want to do man.

Depends what the single box is hosting? If all you need is a SBS and nothing else, I agree with tin but if you want SQL, TS/RDS then VM's.

Out of curiosity, it isn't a Hyper-V host is it?  If it is and you are running a Broadcom NIC you might be interested in this:

Yes, and we updated the drivers after finding a mention of this.  Weird it ran without a hitch for a year before deciding to misbehave.

Yeah I have seen it on two of my sites in the past year, both were running fine for a few years then suddenly the issue appeared.  Not sure if it was simply timing or an update that had an effect but putting the workaround (disabling the VMQ) fixed the issues in both cases.
