In a corporate environment it is not uncommon for Microsoft SQL Server Management Studio (SSMS) for SQL Server 2005 to take over 45 seconds to start as well as lags and delays when opening various windows and dialog boxes from within the application. If you are experiencing this issue, then a quick fix is to add an entry in your HOSTS. file that points crl.microsoft.com to 127.0.0.1
- Exit SSMS
- Press the keys [Win] + [R]
- Enter the following..
- notepad %systemroot%\system32\drivers\etc\hosts. Append the following..
- 127.0.0.1 crl.microsoft.com
- Save the file.
- Start SSMS (ah! much better)
The reason why it is slow is because .Net Runtime tries to contact crl.microsoft.com to ensure that the certificate in various .Net packages that were shipped with SSMS is valid.
If you are behind a firewall/proxy as is the usual case then there is no direct route out to the internet to crl.microsoft.com to validate the certificate(s) and it eventually times out. The wait for the time out causes the delay for each and every package it checks.
With the change to the HOSTS. file, you are forcing the certificate checks to crl.microsoft.com to route to the local host which immediately fails and the certificate checks are ignored.
在昇陽(SUN)被甲骨文（Oracle）收購以後，後者對 OpenSolaris 計畫沒有積極支援的意圖。委員會於2010年7月12日對甲骨文給出「最後通牒」，要求在8月16日派出一位代理人商討計畫的走向，否則將在8月23日的委員會會議中做出回應。由於甲骨文未加回應，委員會於該日達成共識，解散 OpenSolaris 委員會，社區將不再提供新的源碼，計畫的控制權由開發員社區交還給甲骨文。依據甲骨文的反應，可以證實與傳聞相同，他們有意讓 OpenSolaris 計畫死亡。據此，開放源碼社區以原本的代碼為基礎，分支出新的計畫：OpenIndiana和Illumos。
