The instruction at "0x30cb0bad" referenced memory at "0x00000000".

Hi Guys, Today I have faced a new error message with the user. when he tries to upload or edit something in "content editor webpart" in his SharePoint. IE got freeze and he has to terminate the session. Though this was not a SharePoint issue but still i finds it to be somewhat important to discuss.


To resolve this issue, use the following methods in the order in whichthey are presented.

Method 1: Clear cached data in Internet Explorer 7.

To determine whether a performance issue or an error message is causedby corruption in the Temporary Internet Files or in other cachedinformation that is used by Internet Explorer 7, you must clear cacheddata. To do this, follow these steps:
1) Open Internet Explorer 7.
2) Click Tools, and then click Delete Browsing History.
3) In Delete Browsing History, click Delete All.
4) Click to select the 'Also delete files and settings stored byadd-ons' check box, and then click OK.

A progress bar is displayed to indicate that the browsing history isbeing cleared. After this process is complete, test Internet Explorer toverify that it works correctly. If issues still occur, try Method 2.
Method 2: Reset security settings for Internet Explorer 7If you configure security settings to be too restrictive, you mayprevent Internet Explorer 7 from displaying certain web sites. Todetermine whether an issue is caused by overly restrictive securitysettings, revert to default security settings. To do this, follow thesesteps:

1) Open Internet Explorer 7.
2) Click Tools, and then click Internet Options.
3) Click the Security tab.
4) Click Reset all zones to default level, and then click OK.

After you do this, test Internet Explorer to verify that it workscorrectly. If issues still occur, try Method 3.

[If this method does not resolve the issue, you can restore InternetExplorer 7 to its previous security level.]

Note - Overly restrictive settings in third-party software (particularlythird-party security software, such as antivirus, antispyware orfirewall applications) may also prevent Internet Explorer 7 fromdisplaying certain web sites. Review your settings in third-party software.

Method 3: Run Internet Explorer 7 in "No Add-Ons" mode.

Third-party add-ons for Internet Explorer, such as ActiveX controls andbrowser toolbars, are used by some web sites to provide an enhancedbrowsing experience. An error may occur if an add-on is damaged or if anadd-on conflicts with Internet Explorer 7. To determine whether theerror is caused by an add-on, run Internet Explorer 7 in "No Add-Ons"mode. To do this, follow these steps:

For Windows XP:
Start > All Programs > Accessories > System Tools > Internet Explorer(No Add-ons)
For Windows Vista:1) Click Start, and then type Internet Explorer in the Start Search box.2) Click Internet Explorer (No Add-Ons). Internet Explorer 7 openswithout add-ons, toolbars, or plug-ins.3) Test Internet Explorer to verify that it works correctly.

If issues still occur, try Method 4.

If no issues occur, the problem is caused by one of the add-ons thattypically load together with Internet Explorer 7. In this case, use one of the following options:

Option 1: Reset Internet Explorer 7

Reset Internet Explorer 7 to its default configuration. This step willalso disable any add-ons, plug-ins, or toolbars that are installed.Although this solution is quick, it also means that, if you want to useany of those add-ons in the future, they must be reinstalled. To resetInternet Explorer 7 settings, use Method 4.

Option 2: Use the Manage Add-ons tool to determine which add-on iscausing the issueUse the Manage Add-ons tool in Internet Explorer 7 to individuallydisable each add-on to determine which add-on is causing errors. To dothis, follow these steps:

1) Open Internet Explorer 7.

2) Click Tools, point to Manage Add-ons, and then click Enable orDisable Add-ons.

3) In the Show box, select Add-ons that have been used by InternetExplorer to display all add-ons that are installed on the computer.

4) For each item in this list, select the add-on, and then click Disableunder Settings.

5) When you have disabled all the items in this list, click OK.

6) Exit and then restart Internet Explorer 7.

7) If issues do not occur, repeat steps 1 through 3.

8) Click Enable for a single add-on.

9) Repeat steps 6 through 8 until you determine which add-on causeserrors to occur.

After you have used this process to determine which add-on is causingerrors, you can disable that add-on. Or, you can uninstall the softwarethat installs the add-on. You should contact the software vendor thatprovided the add-on for additional troubleshooting and support.

Method 4: Reset Internet Explorer 7 settings

To determine whether a performance issue or an error message is causedby configuration settings, reset Internet Explorer 7 to its defaultconfiguration. This was its state when Windows Vista was originallyinstalled. To do this, follow these steps:

1) Open Internet Explorer 7.

2) Click Tools, and then click Internet Options.

3) Click the Advanced tab.

4) Under Reset Internet Explorer Settings, click Reset.

Issues with Internet Explorer 7 can also caused by the presence ofviruses or other malicious software, collectively known as malware.Since malware can be very hard to detect you want to thoroughly scanyour system for malicious software with /several/ of the better onlinescanners (Kaspersky, Eset, Trend Micro, Panda, Sophos, Symantec etc.)and, if necessary, submit a HiJack This log to one of the expert websites that analyze these logs.
