SQL Query Statement

I am not a database administrator, but the other day i need to extract some data from a database. I can logon to the SQL Database, but I am not quite sure where the data is.

After some browsing around i found out that it can be done using a simple SQL query statement.

Here is the example:
SELECT Name, Comment, CollectionID (fieldname)
FROM v_Collection (tablename)
WHERE Name LIKE 'All Windows%'
ORDER BY Name

Outlook RPC over HTTP doesn't work with 3G or fast connection

When you are out of the office and using Outlook with RPC over HTTP to connect to your Corporate email, you may have to enable the “on fast network, connect using HTTP first, then connect using TCP/IP” on the Microsoft Exchange Proxy Settings.

Example:
You are using 3G USB modem that have speed up to 7.5 MB.(This is most likely not the true internet speed you get, but this what windows detected). Outlook will consider it as fast network. If the above option is not selected, outlook will automatically go with TCP/IP for connection. Your outlook would not be able to connect to the mail server.

However if you put the check mark on, Outlook will go for HTTP and it should be able to connect to the mail server.


Of course the consequence is that you will be prompt to enter your Windows account authentication all the time when you open Outlook whether inside or outside Petrosea Office.


Note:
Outlook determines a user's connection speed by checking the network adapter speed on the user's computer, as supplied by the operating system. Reported network adapter speeds of 128 KB or lower are defined as slow connections. There may be circumstances when the network adapter speed does not accurately reflect data throughput for users.

Tools For DNS Testing and Validation

Here are some of the websites that I often use for DNS validation or testing from external network perimeter.
Whenever you do email troubleshooting, website lookup, and or domain whois, you will find that these websites are quite helpful.

  1. www.dnsstuff.com > This is the best one I think. It has a lot of tools and the result are very accurate and fast. You can query and get almost every information here. However you have to pay to get the service. They are not free anymore. Trial period are available.
  2. www.zonedit.com/smtp.html > You can send email testing from this website for validation or troubleshooting. All you have to do is put the email server MX record, sender address, and recipient address.
  3. www.mxtoolbox.com > Through this tool you can query MX record from a domain name.
  4. http://network-tools.com/nslook > You can do NSLookup query for A record, CNAME, PTR, MX, NS, etc to certain server through this tool.
