  rommon> 

  this is my first experience with rommon, for fix rommon on router /3600/3700/3800 series please follow step bellows

  First issue the dev command in order to see which devices are available on your router:
  rommon 1 >dev
  Devices in device table:
  idname
  flash:flash
  slot0:PCMCIA slot 0
  slot1:PCMCIA slot 1eprom:EPROM
  rommon 2 >
  Next, issue the dir [device ID] command for each Flash or PCMCIA device available, and then look for a
  valid Cisco IOS® software image:
  rommon 3 >dir flash:
  File size Checksum File name
  35823432 bytes (0x804b4c) 0x6ba0 c3845−adventerprisek9−mz.124−10.bin
  rommon 4 >
  Try to boot from that image. If the file is valid, this brings you back to normal operation mode:
  rommon 5 >boot flash:c3845−adventerprisek9−mz.124−10.bin
  program load complete, entry point: 0×80008000, size: 0x804a30
  Self decompressing the image : ###################################
  ########…

  If none of the files are valid, you have to download a new one that uses one of these procedures:

  secure PPTP 

  For the most secure PPTP VPN connections, do the following:

  •	Use EAP-TLS with user certificates or smart cards.
  •	Require the use of the strongest possible encryption.
  •	Use a remote access policy to define who can make a PPTP connection based on group membership (if you are using the Routing and Remote Access service).
  •	Configure PPTP packet filters on your firewall interfaces and VPN server interfaces.

  take from: Microsoft

  Setting secure VPN on client

  • from your vpn setting

  • right-click the vpn setting than click properties

  • on the security tab, click advanced (custom settings)

  • use allow these protocols, tick mark on Microsoft CHAP version 2 than clik ok

  you must have administrator Privilege to follow those steps done
