Resolving Error 501 In Exchange Server

Exchange Server Information Store databases support transaction logging i.e. before committing any data to the database, it is first written to transaction logs. If your database is ever forced to perform recovery, these transaction logs replay and restore the database to a working state. When an Exchange Server Information Store database corrupts, it marks an event indicating the root cause of the issue. You can deduce the problem and thus, take corrective measures to solve it. In cases, when no backup is available to replace the damaged database and ESEUTIL utility also fails to repair, you need to use an effective Microsoft utility that could repair and restore the damaged database.

For an instance, you might receive the below event ID in Application log of Event Viewer:

Date: date Source: ESE
Time: time Category: Logging/Recovery
Type: Error Event ID: 454
User: N/A
Computer: Servername
Description: Information Store (2184) Database recovery/restore failed with unexpected error -501

Cause

Event 454 generally indicates database corruption that occurs while restore or recovery operation. Error -501 corresponds to hexadecimal value 0xFFFFFE0B. It represents JET_errLogFileCorrupt error and shows that the recovery operation has failed because of log file corruption.

Solution

You need to solve the given issue by following these steps:

Check if all database files are consistent. If they are, you can move all corrupted log files that are contained in ExchsrvrMdbdata folder and then try to mount the Information Store
If applying the above step doesn’t solve the issue as databases are not consistent, you need to restore the corrupted databases from backup.
In case, no suitable backup is present, you can execute eseutil /p command to repair the damaged databases

If the error stil persists, use a powerful and safe third-party Exchange Recovery Tool to scan and repair the damaged database. Microsoft Exchange Recovery software are non-destructive tools designed with advanced technology to repair the corrupted database.

What Is Actual Working Of Proxy Server

The most common and popular way to stay on internet nameless is proxy server. To accept incoming request of web and forward it to destination are done by the proxy server machine; these severs acts like a middle men of internet which assist to distinguish your computer and destination server. Each computer get connected to net through proxy server or it is a computer that offers online as well as offline services to permit other system users to use web world. So proxy server serve the role of agent between the client (users computer) and server.
Please dont mix up the concept of a proxy server with a NAT (Network Address Translation). Although they look alike, a proxy server does the work of connection, response, and receives traffic from the Internet. In other words, it acts in support of the client computer. A NAT, on the other side, it changes the original address of traffic coming through it and passes it to the Internet. The computer after the NAT, not the NAT itself, does the work.

Technically the difference between proxy server and NAT is as proxy server use transport level 4 or higher, but NAT using 3rd level.
How It Works:
1.When a user on intranet requested for any web page. Actually it requests to proxy server, which forward it to destination server. It also receive data from net server before the client pc, and it transmits the data to user.
2.Proxy servers maintain log report of total network usage such as download, IP address of accessed websites, date & time of access, URL. E.g. Telnet proxy server can trace each and every data passing through.
3.Some proxy servers have to work with unique users. Many people use Netscape with proxy servers. When such type of software is used, that software must be configured to use it with proxy server. Then only intranet users allow using client software as usual.
4.Proxy server not only work as relay but also it can make secured network in office, home. E.g. a FTP proxy server can configured to restrict any type of miss use, means ban download or upload or both.
5.Proxy server also served as time saver. It keeps the copies of web pages .So when user request for same, proxy server provide that page without contacting to internet server. It save time when time is main factor of work.

Internet Speed Problems – 4 Simple Ways To Speed Up Your Internet Surfing

Surfing the Internet is becoming an essential thing in most of peoples life. Unfortunately, more and more PC users battle with an awfully slow internet speed. The sluggish internet speed will cause much inconvenience to computer users. With the poor speed, you can do nothing but just waste your precious time. Here, I would like to discuss some easy ways to improve internet speed with you guys.

1. Internet Speed Problems caused by Binding too many Agreements on Network Card

Slow internet surfing speed is a usual problem among LAN users because there are too many agreements binding on the Network Card. If a NIC is bound lots of agreements then the computer has to spend more time on identifying which agreement would transmit a certain group of data that passes it. PC users will feel uncomfortable at the moment when they are surfing the Internet. Here is a solution for this situation:

a. Use a Network Card to run only PPPOE agreement to connect ADSL; this will provide the exterior connection of internet.
b. Use another one to run other agreements in order to boost its performance so that the speed of internet surfing would be improved obviously.

2. Internet Speed Problems caused by Unbound TCP/IP Agreement.

Unbound TCP (Transport Control Protocol)/IP (international agreement) may be caused by reasons as follow: a. the driver of Network Card is installed incorrectly. b. There is a problem with quality of Network Card. c. PCI slot is broken. Solution for this situation: You should uninstall NIC driver in the Device Manager at first—-reinstall the driver after you reboot your computer. If you still fail to improve the internet speed with this solution, please change a PCI slot for Network Card or change a new one.

3. Internet Speed Problems caused by low quality of telephone line.

If the phone line is affected by some bad extraneous factors, network device will adjust client access rate automatically and dynamically according by the quality of line and transmission distance. The Internet surfing Speed also will be affected by the export bandwidth, the website line from opponents and the device configuration if you try to visit foreign website.

4. Internet Speed Problems caused by too much installed Internet Explorer plug-ins.

Internet Explorer plug-ins would be installed or loaded on your computer automatically when you open Internet Explorer and visit website. Surfing speed of course will be slowed down by too much Internet Explorer plug-ins.

It includes the instance-wide meta data like logon accounts, linked servers, system configuration settings, and endpoints.

Thus, Microsoft SQL Server can’t start if master database is missing, damaged, or unavailable. Corruption of the master database leads to critical data loss situations and requires .

Microsoft SQL Server facilitate checking the integrity, both logical and physical, of all objects in specified database through DBCC CHECKDB. It includes three modules- DBCC CHECKALLOC, DBCC CHECKTABLE, and DBCC CHECKCATALOG, which are used to perform specific operations. If you run DBCC CHECKDB on any database, you need not run any of its modules on the affected SQL Server database. It also validates contents of indexed view, link-level consistency among file system files/directories and table meta data, and Service Broker data in SQL database.

However, the DBCC CHECKDB can not handle database corruption in all cases and thus your master database may remain inaccessible in those cases. The problem generally occurs in case of severe corruption to the database.

points to the data row identified by ().
CHECKTABLE found 0 allocation errors and 1 consistency errors in table ‘syscolumns’ (object ID 3).
