Netgear issues with BSNL Dataone Broadband
I was unable to browse some websites, including yahoo.com through my Netgear DG834G ADSL2+ modem with BSNL Dataone Broadband connection.
The problem was due to WAN MTU Size. On changing the default MTU 1492 bytes to 1430 bytes, all websites started loading.
From Netgear:
Setting MTU size is a process of trial-and-error: start with the maximum value of 1500, then reduce the size until the problem goes away. Using one of these values is likely to solve problems caused by MTU size:
- 1500. The largest Ethernet packet size; it is also the default value. This is the typical setting for non-PPPoE, non-VPN connections. The default value for NETGEAR routers, adapters and switches.
- 1492. The size PPPoE prefers.
- 1472. Maximum size to use for pinging. (Bigger packets are fragmented.)
- 1468. The size DHCP prefers.
- 1460. Usable by AOL if you don't have large email attachments, etc.
- 1430. The size VPN and PPTP prefer.
- 1400. Maximum size for AOL DSL.
- 576. Typical value to connect to dial-up ISPs.
Happy Browsing

Stop Blue Screen 0x0000007E memory dump error
If you are experiencing Stop Error 0x0000007e (0xc0000005, 0x89c3e6e4, 0xb90d9a40, 0xb90d973c) regularly & exhausted on finding a solution try this :
Solution 1:
Try removing external cards(Sound Card, Network Card etc) of your mother board & check whether the issue is solved.
You can also try by uninstalling each Card driver.
Solution 2:
Any other conflicting/malfunctioning driver may also leads to this issue.
1. In Run, type sigverif & click Ok.
2. In Sigverif tool window, click Advanced, click Look for other files that are digitally not signed, click browse & select Windows\System32\Drivers folder, click Ok.
3. Run Start.
4. In the list of unsigned drivers, trace which are unknown & non essential drivers. Move the sys file to a backup folder. (Be careful, while moving the driver. Move only unsigned driver file)
5. Restart the system & make sure all are working normal without these drivers.
Solution 3:
Make sure you have sufficient hard disk space.
Done.
I Hope & Wish you will not get that Stop error again.
Long Live Windows!

MSSQL & Event ID: 17137
In Event Viewer > Application, If you have noticed Thousands of Events with details "Starting up database.." Event ID: 17137, here is the solution :
Make sure to set all the database in your SQL Server as Auto_Close=False. By default in SQL Server Express Editions, Auto_Close was set to True. If Auto_Close is true, SQL Server close the DB when the last connection is closed. So the databases were stopped & started regularly.
To Set Auto_Close = False
In SQL Server Manager > Right Click Database > Properties > Options, you can find the option.
OR
ALTER DATABASE SET AUTO_CLOSE OFF
