Have you tried cannot open a attachment in Outlook?
There may be occurs by too many same file name in SecureTemp folder.
Outlook will automatic save a copy in SecureTemp folder when you open the attachment.
When you try to open the attachment with same name in Outlook, Outlook will create a copy in SecureTemp folder and add the number behind the file name (e.g. abc (1).doc, abc (2).doc....).
If there a more than 100 same file name (e.g. abc (100).doc), you will not able to open in outlook,
so you have to find out the SecureTemp folder location and delete the file.
Find SecureTemp
At start menu, Run, type regedit to open the registry editor.
Browse to this key:
HKEY_CURRENT_USER\Software\Microsoft\Office\xx.0\Outlook\Security
OutlookSecureTempFolder value
(Change xx to reflect the version number of Outlook. 14.0 = Outlook 2010; 12.0 = Outlook 2007; 11.0 = Outlook 2003 and 1.0 = Outlook 2002.)
Double click on OutlookSecureTempFolder to open the value then copy the path. Paste it into the address bar of Windows Explorer to open the folder.
This folder is normally hidden by the file system.

Can't see Security tab for a folder in XP?
If the security tab isn't visible on any of your folder properties in XP, you may have "Use Simple File Sharing" selected in your Folder Options.Open Explorer and go to Tools>Folder Options.
Click the "View" tab and scroll to the bottom of the listbox with the heading "Advanced Settings".
Clear the "Use Simple File Sharing" checkbox.
Cisco Command
近期因為要設定Cisco 2950 Switch,所以把指令重温一遍,以下係小小的總結:
1.設定主機名稱
Switch(config)#hostname 主機名稱
主機名稱(config)#
2.設定密碼
======================enable密碼===============================
Switch(config)#enable password level 1 密碼 //密碼最少4個字元,最多8個字元,level為1-15
Switch(config)#enable secret 密碼 //加密模式密碼,如有設定,會蓋過enable密碼
======================console密碼==============================
Switch(config)#line console 0
Switch(config-line)#password 密碼
Switch(config-line)#login
Switch(config-line)#exec-timeout 0 //閒置登出
Switch(config-line)#logging
synchronous //訊息同步
=====================telnet(vty) 密碼=============================
Switch(config)#line vty 0 15 // 0-15 共有16條vty線路
Switch(config-line)#password 密碼
Switch(config-line)#login
=============================================================
3.介面設定
Switch(config)#int FastEthernet0/12
Switch(config-if)#description 介面描述 //在sh int 及 sh run int 內可看到
Switch(config-if)#duplex auto //設定雙工模式,預設auto
Switch(config-if)#speed auto //設定速度,預設auto
Switch(config-if)#^z
Switch#sh running-config
!
interface FastEthernet0/12
description 介面描述
!
4.啟動介面
Switch(config)# int 介面
//介面為e0,S1/0,fa0/15,atm2/3.14,...等
Switch(config-if)#no shutdown //啟動介面
Switch(config-if)#^z //ctrl+Z 表示快速寫入config
5.ip 設定
Switch(config)#interface vlan 1
Switch(config-if)#ip address 192.168.0.250
255.255.255.0 //設定ip及Subnet Mask
Switch(config-if)#no shutdown
Switch(config-if)#exit
Switch(config-if)#ip default-gateway 192.168.0.254 //跨網段管理
Switch(config-if)#^z
6.設定SSH
Switch#configure terminal
Switch(config)#ip domain-name example.com
Switch(config)#crypto key generate rsa
Switch(config)#username netadmin password
netadmin
Switch(config)#ip ssh version 2
Switch(config)#line vty 0 15
Switch(config-line)#login local
Switch(config-line)#transport input ssh
telnet
7.安全設定
1.Port security 只針對Access mode的Port設定
2.enable port security
3.(Optional)設定最大MAC數量,預設 1 show不會顯示,Cisco設備預設值通常不顯示
4.違規時switch的動作violation{shutdown預設 | restrict |
protect}
5.1~4只防阻MAC Flooding攻擊,每一個port只能有1個MAC通過,但還不能防止非法MAC接到設備上,把合法
MAC寫到table,只要MAC有錯port就會 shutdown
Switch#show mac-address-table //在Switch上查看MAC-Address-Table
將介面啟用Port-Security,指定只學習一筆MAC,使用Sticky方式學習MAC,並設定違規處理方式為Shutdown
Switch(config)#interface fastEthernet
0/18 //指定介面
Switch(config-if)#switchport mode
access //將Port改成Access Mode
Switch(config-if)#switchport
port-security //啟用Port Security
Switch(config-if)#switchport port-security
maximum 1 //設定最大的MAC數量
Switch(config-if)#switchport port-security
mac-address sticky
Switch(config-if)#switchport port-security
violation shutdown //預設,處理err-disabled
或
Switch(config-if)#switchport port-security
violation restrict //合法MAC接回就會通
=================================================================
Switch(config-if)#do sh port-security //檢查有哪些Port啟用Port-security
Switch(config-if)#do sh port-security
address //檢查有哪些Port有sticky或手動輸入MAC Address
Switch(config-if)#do sh port-security
interface fa 0/18 //檢查Fa0/18的Port-security的詳細設定
Switch(config-if)#do sh int fa 0/18 //檢查Fa0/18的介面狀態(注意err-disabled)
=======================range 多個Port設定=============================
Switch(config)#interface range fastEthernet
0/4 - 7 , fastEthernet 0/9 - 15
Switch(config-if-range)#switchport mode
accesss
=================================================================
將Fa0/18接另一台PC,因為Fa0/18有啟用Port-security,並將之前自動學習到的MAC以Sticky記錄,檢查
Fa0/18的介面狀態會出現err-disabled:下面為解決方法
Switch#sh int fa 0/18
FastEthernet0/18 is down, line protocol is
down (err-disabled)
Switch#sh run | begin FastEthernet0/18
!
interface FastEthernet0/18
switchport mode access
switchport port-security
switchport port-security mac-address sticky
switchport port-security mac-address sticky
0020.E22D.9B05 //此行為出問題的MAC address
!
Switch#conf t
Switch(config)#int fa 0/18
Switch(config-if)#no switchport
port-security mac-address sticky 0020.E22D.9B05
Switch(config-if)#do sh int fa 0/18
FastEthernet0/18 is down, line protocol is
down (err-disabled)
Switch(config-if)#shutdown
Switch(config-if)#no shutdown
Switch#sh interfaces status //檢查所有界面的狀態
8.停用網域名稱反查
Switch(config)#no ip domain-lookup
9.組態設定
將Switch的IOS與startup-config複製到TFTP
Switch#sh flash
Switch#copy flash tftp
Switch#copy running-config
startup-config //設定寫入NVRAM(組態檔)
Switch#copy startup-config tftp
=========================================================
Switch#erase startup-config //刪除啟動組態檔
Switch#delete vlan.dat
Switch#reload
或
Switch#delete nvram
//刪除啟動組態檔
10.CDP相關設定
=======================查詢鄰近設===========================
Switch#sh cdp neighbors (Device ID =>ro)
Switch#sh cdp entry router
==================將Switch的介面CDP功能關閉=====================
Switch(config)#int fa 0/5
Switch(config-if)#no cdp enable
=====================將設備dcp功能關閉========================
lab2(config)#no cdp run
=========================================================
