When i start up my comp I get this message rundll32 has caused an error in newdotnet3_23.dll----rundll32 will now close. How do I get rid of this the computer seems to be running fine once I close it.

Hi,
Dont worry by seeing the solution, its very big and it worked for me
last week.

Here it goes
************************************************** *********
First create a backup Registry file

1. Click Start
2. Click Run
3. Type in "regedit"
4. Click OK
5. Highlight "My Computer" on the left
6. Click the Registry menu at the top and select "Export Registry File"
7. Name the file "backup" and save it to your Desktop. [This is just in case you make a mistake in the procedures below. Should you do so, locate the "backup" file on your Desktop and double-click it. Select Yes and your registry will be restored.]

Check for New.net Startup:

1. In the left pane of the Registry Editor, under HKEY_LOCAL_MACHINE, click the "+" sign next to Software
2. Click the "+" sign next to Microsoft
3. Click the "+" sign next to Windows
4. Click the "+" sign next to Current Version
5. Click on the Run folder
6. On the right, locate the line that reads "New.net Startup" and delete it

Remove "New.net Application" from Add/Remove Programs:

1. Under the same Current Version folder from above, click the "+" sign next to Uninstall
2. Locate New.net Application and delete it

Remove the New.net software folder:

1. In the left pane of the Registry Editor, under HKEY_LOCAL_MACHINE, under "Software"
2. Locate the "New.net" folder and delete it

Close the open folders above by clicking once on the small "-" signs next to them.

Locate "Catalog Entries" folder:

1. Under the HKEY_LOCAL_MACHINE folder, click the small "+" (plus) sign next to System
2. Click the small "+" (plus) sign next to CurrentControlSet
3. Click the small "+" (plus) sign next to Services
4. Click the small "+" (plus) sign next to WinSock2
5. Click the small "+" (plus) sign next to Parameters. You should see 2 folders, "NameSpace_Catalog5" and "Protocol_Catalog9".
6. Click the small "+" (plus) signs next to both of them
7. Inside both folders, you should see a "Catalog_Entries" folder. Open each of them.
8. Within each of those folders are numbered folders (i.e. 000000000001, 000000000002, etc.)

For the "NameSpace_Catalog5" numbered folders:
A. First, make note of how many folders there are
B. Highlight the first one
C. On the righthand side, locate the line "Library Path"
D. In that line, the rightmost column should begin with something similar to "C:\windows" or "%SystemRoot%".
E. Locate any of the numbered folders that read "C:\windows\newdotnet2_109.dll" (or similar) in the "Library Path" line
F. Delete only those folders referring to "newdotnet"
G. If needed, rename each numbered folder so that they are all consecutive. For example, if there were 4 folders and you deleted folders the first 2, you will need to rename the remaining folders 00000000001" and "000000000002".
H. Do this by right-clicking the folder name, left-click Rename and then type in the new number (be absolutely sure you don't delete any of the zeros).
I. Next, highlight the "NameSpace_Catalog5" folder on the lefthand side.
J. On the right, locate the "Num_Catalog_Entries" line. At the end of this line is a number in parentheses.
K. Edit that number by doing the following:
i. Double-click "Num_Catalog_Entries"
ii. In the small pop-up window, select "Decimal"
iii. Edit the value of the number on the left to reflect the number of remaining folders (in the case of the example in step G above, you would enter 2)
iv. Click OK

For the "Protocol_Catalog9" numbered folders:
A. First, make note of how many folders there are
B. Highlight the first one
C. On the righthand side, you will see a line beginning with "PackedCatalogItem". Double-click on that word and a small window will pop-up.
D. In this window, several columns appear with numbers and letters. At the top of the last column appears a path that will look something like, "C:\WINDOWS\NEWDOT~.DLL" or "% SystemRoot%" followed by a long list of characters.
E. Look through each of the numbered folders and delete only those that indicate "C:\WINDOWS\NEWDOTNET2_109.DLL" (or similar) in the "Edit Binary Value" window described above.
F. Rename each remaining numbered folder so that they are all consecutive. For example, if there were 13 folders and you deleted 2 of them, you will need to rename the remaining folders "000000000001" through "000000000011".
G. Do this by right-clicking the folder name, left-click Rename and then type in the new number (**be absolutely sure you don't delete any of the zeros)
H. Next, highlight the "Protocol_Catalog9" folder on the lefthand side.
I. On the right, locate the "Num_Catalog_Entries" line. At the end of this line is a number in parentheses.
J. Edit that number by doing the following:
i. Double-click "Num_Catalog_Entries"
ii. In the small pop-up window, select "Decimal"
iii. Edit the value of the number on the left to reflect the number of remaining folders (in the case of the example in step F above, you would enter 11)
iv. Click OK

Again, you may close all open folders. Close the Registry Editor. Your changes will be automatically saved. Reboot your computer and attempt to access a website. See Step 6 (Registry backup) above if you experience other unusual computer problems. If your Internet access has been restored, we recommend you delete the registry backup file by doing the following:

1. On your Windows desktop, locate the "backup" file that was created in the Backup Registry procedure above.
2. Delete the file and remove it from your Recycle Bin also.
