Проблем с мрежа защитена с парола win7-XP

[ru-boy]

Мързи ме да пиша, но нещата са лесни и не са така страшни както ги описваш.
Обратно на съвета на MitkoS може да минеш с:

- само NETBIOS, или
- само с IPX/SPX

Вярно, че са "артефакти", но работят перфектно, за това са създадени и ги има като опция.
Избираш само един от двата, това са надеждни и прекрасни протоколи, които не изискват познания за настройка.

Може да сложиш и само TCP/IP v.4 но трябва да зададеш адреси.
Препоръчително е да не слагаш отметки на всички протоколи съвсем не са нужни.
Избираш с кой ще работиш и слагаш отметка само на него.
Мисля, че съвършенния в-т е в комбинацията TCP/IP и IPX/SPX.
Обаче на ХР-то слагаш TCP/IP и IPX/SPX а на 7-цата само IPX/SPX. Защо е друг въпрос.
Така би трябвало да тръгне веднага. Никакви други отметки.
Ясно е, че може и само с TCP/IP, но явно нямаш представа как да го направиш, въпреки, че е лесно.
Вземи си и един мрежов скенер за по-лесно откриване на ресурсите на другия/те компютри.
Ето този е перфектен (видно и от името му ;-) ) http://www.softperfect.com/products/networkscanner/
Понякога (както при теб) става объркване с акаунтите и имената и с този скенер ще видиш веднага кое е видимо и с какви ресурси за секунди а не да се чудиш какво да правиш.
Май го обясних много разхвърляно, ама ...

Е да де, ама работата е там, че "проблеми с протокола няма".
Ако имаше, то съобщението за грешка щеше да е :
"Windows can not access \\adi".

В момента грешката е "неизвестно потребителско име или парола", което е много "по-високо" от протокола.

Най-вероятно, при конкретния Win 7, е допълнително някак си е включено някакво допълнително полиси за сигурност на връзката, което не се поддържа в XP. Но нямам идея кое и къде точно. Евентуален преглед в Event Viewer, може и да може да подскаже нещо.

ПП.
Компютрите актуализирани ли са по отношение на Windows Updates ?

ПП2.
Ей това е от WIn7Pro с дифолт настройки. Без проблеми от тази машина се осъществяват връзки към XP със съответните акаунти. Евентуално можеш набързо да свериш и провериш за разминавания с настройките при теб

Сега трябва да изляза от форума и ще се върна утре някога

"Event Viewer" не знам да е помогнал на някого за нещо, освен тема за упражняване на философия.
Идеята с протоколите е друга, но явно е трудна за осъзнаване.
Има си няколко принципа за мрежите и защитите и не е нужна магия, за да работи.
Спазваш 2-3 правила. Само толкова.

Компютрите са актуализирани до последният ъпдейт.
Относно Policy Security Setting настройките са така.
MitkoS споделянето при теб с кроснат кабел и 2 лан карти ли е?

[MitkoS]

С най-обикновен суич съм, но това няма (според мен) значение, заради типа на грешката при теб.

Ако имаш съмнения за лоши кабели и лоши физически връзки, то това най-лесно се проверява с командата ping:

Accessories/Command Prompt
>ping adi /t

Не трябва да има никакви загуби (Request Timed Out), когато става въпрос за малка локална мрежа.


ПП.
След всичката изписана информация, най-много се съмнявам за защитна стена в антивирусната програма - в смисъл уж е спряна, ама продължава да работи и да пречи на връзката.
Що не вземеш направо да я деинсталираш (времено поне) !?

[krasilz]

След преинсталиране на антивируса на XP-то се оправи всичко. Благодаря за отделеното внимание на всички. MitkoS
