我将生成的网站放上服务器后，没有任何规律的出现如下错误
Server Error in '/' Application.

发生的频率不是特高，没有什么规律性。有的时候已登录网站就这样，有的时候是点击某些页面的也会出现。请问这个是什么错误，怎么解决呀？
这个是不是和web.config中的<machineKey>有关系？我没有指定这个元素！！
另外我加入了<authentication mode="Windows"/>！！

你的服务器是几台机器组成的啊.

[w161134025]

代码太多,很吓人...
帮你顶

[sftl25789]

忘记说了，服务器就一台，windows 2003+IIS6+Sql server 2000数据库
开发用的VS2005+Sql server 2000数据库

路过.看不懂

[Jack123]

A way to overcome the problem is to set in web.config

<pages enableEventValidation="false" viewStateEncryptionMode ="Never" />

Just note the security implications of these!

or you can adjust the nested form in the master page, everything will be OK.

请楼主参考以上两篇文章

这错误也太多了吧

[mjjzg]

你先放到本地运行，看有什么错误，慢慢排吧，本地排完了，再上传到服务器，看有什么错误，你这直接上传到服务器错误太多

最有可能的就是Web.Config配置错误

最有可能的就是Web.Config配置错误

[ojekleen]

看上去就像因为服务器集群时各服务器的machingKey不同而导致ViewState的读写错误。。
楼上的方法看看行不行。

发布的目录有问题,那个生成的config配置文件应该放在要发布的网站的根目录下

很感谢你的帮助，但是我加入了<pages enableEventValidation="false" viewStateEncryptionMode ="Never" /> 后，网站立刻报错了，错误如下
Server Error in '/' Application.

我也找到过这个方法，不过和你的不太一样，如下
<pages enableEventValidation="false" viewStateEncryptionMode ="false" />
改过后，网站是正常了，但是不知道有没有效！

[qinhl99]

修改当前页面的@page属性，添加enableEventValidation="false" enableViewStateMac="false"
或者在web.config里添加 <pages enableEventValidation="false" enableViewStateMac="false" />

我的网站现在也有这个问题，但我感觉好像是session的问题
