Hi

We encounter same problem on our developers computers and find out that problem relates to application & device control component (again!) and if you remove this component from installation everything will be fine.

@reza

Thanks...

We have tested the same with each & every component & came to conclusion that Application & device control is having the issue & that is the BUG of SEP

Once again thanks for ur comment.

Any how i want the hotfix for this issue from symantec.

Without Application & device control i will not able to monitor USB & other applications.

Hi Ramji,

It looks like, when you install a managed client, your software does not work. However, installing an unmanaged client seems to work fine. Can you try one thing, install a managed client. Disable the service called Symantec Management Client. Then reboot the computer.

Now, try to use the software. Let us know if this works.

Also, please attach a debugger to your software's service when you install a managed SEP client, so we can analyze the crash debug logs if a crash happens.

You can refer to the following link:

I suspect it has to do with a paticular set of SEP policies, as we've not seen any issues here with .net.

try withdrawing the appliaction and device control policy. it resolved my issue for now. support is investigating it.

I had created a test group & removed all the policies except antivirus-antispyware & Liveupdate policy.

Then moved the PC's to that group & checked , same issue .net crashed.

Installed one fresh replica of the .net developper PC & given to Symantec technical support engg. he tried various times.
result was the same. .net crashed.

2 more options to try could be:

1. to withdraw the NTP policy as well for the same group (if resolves, you may try adding back the app. & dev. policy)
2. to uninstall NTP completely from the necessary clients.

until the issue is resolved :(

regards,

A small update !!!!

Shown demo to backline support team & they are working on it.

I opened new case about this issue.
After working with the tech for a little bit, we figured out it is an issue with the "Application & Device Control" in SEP RU5.

Systems I was having issues with:
Windows XP Pro SP3
Windows Server 2003 Standard R2 SP2

I was able to install the following components and .net framework is working:
Antivirus and Antispyware, Anvirus Email Protection - Pop/SMTP, Network Threat Protection, Proactive Threat - Trusacan

Right now wait for resolution to this issue, since I would like App & Dev Control.

around two month passed without a solution?? Where are you symantec developers?

still having problem with application and device control component and .net applications. We need solution.

After all they already got paid for the product....

hello guys,

In my case, they've developed a sysplant.sys and it worked. Blue screens are gone for now.

This should probably be applied on MR6. Does anyone know when is it going to be out?

Just ran into this issue with our dev team.  Glad to have found this post.  I created a group that had the same policies as before, but removed the application & Device module, rebooted the PCs and the aspnet / IIS errors were gone.

More info on this issue can be found in a different thread. Jon Dorset did a good job of summing up the issue.

Further to Dan Carrera's comments; I too have an issue whereby some of my developers can not use their applications designed with .net framework and IIS. Please excuse my lack of terminology as I'm not a developer.

If I follow Dan's advice and create a policy without the application and device control does this have a detrimental effect on SEP protecting my developers systems?

yes it would , But if that is the case you can revert back to MR4MP2.

I think after 6 month of release of RU5 we requrie a fix or at least a timeline....

New MR should be out this month. That's what says in the roadmap, but it may change...

A lot of changes are coming though, we'll need to do thorough testing...

Yes it expected this month. and it should take care of the application crashing issue...... Hopefully :))

There is a document too 

After migrating a Symantec Endpoint Protection (SEP) 11 client to Release Update (RU) 5 or installing RU5, .NET Framework applications fail to work properly

Got Solution in  RU6. But afraid of RU6 for any new issues.
