Hi All,We have observed that whenever we enable IPSec between our Printer and Windows 7, DPWS Scan (WSD Scan) using Windows Fax and Scan appilcation seems to be not working properly. We are getting an error "No Scanners were detected".We also observed that other Win7 which dont have IPsec is working properly.Observation1: Printer is sending "Hello" when it is coming up with IPsec.Observation2: Win7 is not sending subscription message immediately. It takes around 10 minutes to send it. Whereas other Win7 PC which dont have IPsec sends the subscription message immediately.Please let me know if anyone had faced similar issue. I think issue is same on Win vista also.Thanks in Advance,Arun
