We know have an updated aswTdi.sys version that may solve the problem.
How to install it:
- Download the file http://www2.asw.cz/~vlk/aswtdi.zip
- Unpack its contents to the following locations:
a) \setup\inf
b) \windows\system32\drivers
(overwrite existing versions)
- Restart the machine.
This build should solve problems with multiple connections being redirected in loop (generating e.g. a large number of timeout messages or 100% CPU load in ashMaiSv.exe) in conjunction with certain personal firewalls (such as Norton PF).
Thanks
