some stupid questions:
* is your network connection set to Public or Private? Typically you'd want it to be Private (assuming you're using an in-office network connection)
* Is this on a domain? or is using "peer-to-peer" mode with workgroup name?
* if using workgroup, when the username was created on the workstation, was it registered with an E-mail address? (a "feature" introduced in Windows 8 that could result in headaches if your network login username/password isn't identical to the one used for for E-mail -- which would likely be the case if the E-mail is on an offsite service).

>>Hi Dorris,

>>I remember reading some time back a similar complain about another version in MSDN forum. Did you try to disable Intellisense (if there is an option)?

>>Also, are you connecting to local DB or remote?
>>
>>My suggestion to you would be to try asking this question in MSDN SQL Server forums (probably Setup & Upgrade), there are lots of real experts hanging in these forums that would know the answer or you'll get attention from MS people.

>>If you post there, can you please post here the link for the reference?

>>Thanks.
